Abstract

The invention relates to a time switch (1) with at least one first and one second elastic spring element (22, 23) that are both provided with at least one switch contact (24, 25). The time switch further comprises a rotation-driven drum controller (3) that is provided with a plurality of adjustable switch elements (11, 12) which displace a switch lever (13) from an inactive initial position to a switching position, thereby triggering a switch operation of the spring elements (22, 23) with their switch contacts (24, 25). When the drum controller (3) continues to rotate, the switch lever (13) abruptly falls back into its initial position, thereby abruptly disrupting the switch contacts (24, 25). In order to effect an abrupt closure of the switch contacts (24, 25), a locking lever (35) is provided between the spring elements (22, 23) which, in a first switch phase and under the effect of a pre-stress, maintains the two spring elements (22, 23) at a certain distance to the switch contacts (24, 25) and which, during a second switch phase, abruptly releases the second spring element (23) so that it can abruptly close the switch contacts (24, 25).

Description

TIME SWITCH WITH ELECTRIC SWITCH MECHANISM {TIME SWITCH WITH AN ELECTRIC SWITCH MECHANISM}

German Patent No. 27 54 212 B1 discloses a time switch of this type, which switches at least one first and second switch contact disposed on the first and second elastic spring elements in the form of a leaf spring. Include. The time switch is provided with a double switch which is driven in one rotational direction as a drum controller. The switch includes two coaxial gear rims displaced from one another by one-half pitch. The gear rims each have a ratchet for quickly actuating one or a plurality of spring elements of the switch contact to effect a switching operation. In order to obtain the exact switching point possible without adjustment work, a switch lever is provided between the gear rim and the spring element to be actuated. The switch levers are respectively engaged with one of the double star gear rims by ratchet noses formed in the switch levers. By means of the gear rim the switch levers are alternately or in turn displaced, and the ratchet of each gear rim suddenly retracts to its initial position after passing through the associated ratchet nose of each switch lever, causing a sudden switching action.

The switching time obtainable by the known time switch is given by the number of ratchets of the gear rims which are actually displaced from one another. Thus, with the time switch, different switching times can be achieved only by replacement of the tooth boundary. That is, in the above known time switch, the switch lever is suddenly retracted to its initial position, so that an accurate switching time is obtained because the associated elastic spring element of the switch contact is suddenly operated, but a different switching time cannot be set. .

In order to set such different switching times for various purposes, time switches are known, for example in German Patent No. 28 13 069 C2, in which a drum controller is used. The drum controller includes a switch element that can be switched from the acting position to the non acting position. The switch lever is actuated during rotation of the drum controller by the switch element in the acting position. The switch lever again operates the micro switch. Thus, the number of switchable times that can be set depends only on the number of switch elements arranged on the outer periphery of the drum controller. The larger the number of the switch elements, the smaller the interval between individual switching operations can be set. In the known time switch, the switch lever is formed as a double arm lever. The lever is fixed to the switch bar of the micro switch by a spring. By means of the switch element the lever is displaced from the initial position to the switching position as opposed to the force of the spring, whereby the switch bar of the micro switch is activated. When a plurality of switch elements are switched to the active position, the lever slides the outer circumferential surface of the switch element during rotation of the drum controller until one or a plurality of switch elements connected to the inactive position in its acting position are obtained. At the end of the last active switch element the lever suddenly retracts back to its initial position, so that in the switching operation the micro switch is suddenly opened again or connected to its initial position. As the drum controller continues to rotate, the nose of the lever moves again against the connected switch element in the active state and is relatively slowly displaced from its initial position to its switching position. The disadvantage here is that the microswitch also works very slowly when the lever is moved very slowly, so that the switching position or switching timing can be determined very inaccurately.

For the fast switching operation of the switches, so-called snap switches operating according to the top dead center principle are known (DE 38 25 308 A1). The switch includes a rocker connected by a lever. Since the switching direction of the switch lever is suddenly given by the switch lever itself when the switch lever is retracted to its initial position, the switching position can be accurately scheduled. However, when the switch lever strikes the switch element connected in the active state, the timing at which the rocker suddenly switches from its inactive position to its active cannot be accurately determined. Thus, the switching device with such a step switch includes an adjusting device for setting the correct switching point. In addition, the total power in the rotor of the snap switch is transferred through the support of the rocker, which can cause combustion of the support itself when the switching current is high. This also means that the snap switch with the rocker is badly worn. In addition, the switching force on closing of the snap switch is extremely small, so that the best contact of the snap switch cannot be reliably made.

The present invention provides at least one first and second resilient spring element each having at least one switch contact, and a plurality of switch elements each selectively adjustable to an actuated or inactive switching position relative to a rotatably supported switch lever. A rotary drive drum controller having a rotational force, the switch lever being displaced from the inactive initial position to the switching position by the switch element, wherein the switch contact of the first spring element contacts the switch contact of the second spring element. Thereby performing a switching operation, wherein the switch lever is suddenly retracted to its initial position when the drum controller is continuously rotated, so that the switch contact is quickly disconnected.

It is an object of the present invention to provide a switch time that can be variably set using an elastic spring element with a switch contact, and a time switch in which two switching operations or switching points, i.e. the possibility of precise setting of the connection and disconnection of the electrical switch can be obtained To provide.

The object according to the invention is provided with a locking lever which is moved in the direction of the second spring element by a first spring element actuated by the switch lever during the closing operation, the locking lever being moved during the first switching phase of the closing operation. Positively engaged with the second spring element by the locking nose in the blocking position, the two spring elements with the switch contact being held at predetermined intervals from each other under prestressing action, and the locking lever is second switching following the first switching step From its blocking position during the step, displaced by a displacement element operatively connected with the locking lever during at least the second switching step, achieved by sudden release of the second spring element of the second switch contact for sudden closure of the switch contact do.

With the design according to the invention of the time switch, accurate switching of the switch contacts for connection or disconnection of the consuming device is achieved at a predetermined time. For this purpose, a locking lever is provided which is moved in the direction of the second spring element by the first spring element actuated by the switch lever during the closing operation. During the first switching phase of the closing movement of the first spring element, the locking lever is positively connected with the second spring element via the locking nose so that the switch contact of the second spring element is intended for the switch contact of the first spring element. Maintained at intervals. That is, the locking lever is in the blocking position during the first switching phase of the closing action and positively engages the second spring element by the locking nose. The switch contacts of the two spring elements are held at predetermined intervals from each other under prestressing action. If the drum controller continues to rotate, a second switching step acting in the same direction is followed by the first switching step. In the second switching stage the locking lever is displaced from its blocking position by a displacement element operatively connected with the locking lever during at least the second switching stage. By this displacement, the locking contact is quickly closed by the locking or blocking engagement between the locking noses of the locking levers being abruptly separated from the second spring member of the second switch contact, for example by turning of the locking levers.

That is, the locking lever is in the blocking position during the first switching step, in which the switch contacts of the two spring elements are held at predetermined intervals from each other under prestressing action by the locking lever. The locking lever engages the first spring element of the second switch contact. In the first switching stage the switch lever is extremely slowly displaced due to very little rotation per unit time of the drum controller by the switch element connected in the active state of the rotary drive drum controller. The displacement causes the first spring element of the first switch contact to be gradually moved in the direction of the second spring element of the second switch contact by the switch lever. However, the two switch contacts of the first spring element and the second spring element are not in contact with each other due to the locking lever placed in the blocking position between the spring elements. At the end of the first switching stage the two spring elements are under constant spring elastic prestress. At the beginning of the second switching stage, which is directly followed by the first switching stage in time, the locking lever is displaced from its blocking position in accordance with the increase in the adjusting movement of the spring element. At the end of the second switching step the locking lever releases the second spring element of the second switch contact, so that the switch contact is suddenly closed. The displacement of the locking lever is via a displacement element, which can be, for example, a fixed adjustment peg or an inclined surface depending on the placement and support of the locking lever. The locking lever slides along the displacement element during the second switching phase of the closing motion.

As is known, in this time switch the inherent switch lever comprises an adjacent sensing finger on the outer circumferential surface of the drum controller. This switch element of the drum controller displaces the switch nose radially outward with respect to the drum controller, so that the switch lever is pivoting. By the swinging movement, switching of the switch contact of the spring element is caused. The displacement is generally extremely slow, because the switch nose forms an inclined surface, by which the switch nose is along the switch element connected in an active state during the slow rotation of the drum controller for the displacement. This is because it slides outward. Since the majority of the switch elements of the drum controller are connected in an active state, the active switching position of the switch lever is maintained until the last active connected switch element passes through the switch nose of the switch lever. Immediately after the end edge of the last switch element passes through the switch nose, the switch lever abruptly retracts back to its initial position because the switch nose suddenly falls back radially inward. This sudden retraction simultaneously releases the first spring element of the first switch contact again abruptly, so that it retracts back to its initial position. Since the locking lever is locked to the second spring element again during the retraction to the initial position, a new switching operation for the closing of the switch contact can be started.

With the design according to the invention, the switching point for connection or disconnection, ie for closing or disconnecting the switch contacts, can be very precisely scheduled. In particular, there is no need for an additional adjustment device for determining the switching timing. Due to the fast closing and opening of the switch contacts, combustion of the switch contacts themselves rarely occurs. Furthermore, by the thickness design of the spring element or the elastic design of the spring element, the switching force or contact force between the switch contacts is clearly determined in a simple manner, so that the best contact is always guaranteed.

By means of the design according to FIG. 2, a time switch according to the invention can be used for the accurate switching of the energy supply from the first consuming device to the second consuming device. For this purpose, a third spring element having a third switch contact is assigned to the first spring element and the second spring element. The switch contact of the third spring element is in permanent electrical connection with the fourth switch contact disposed on the second spring element until the second spring element is suddenly released from the locking lever during the second switching step. In order to divert the energy flow from the third spring element to the first spring element through the second spring element, the locking lever comprises a switch finger, by which the switch contact of the third spring element is connected to the second spring element. After a sudden release it is maintained at a predetermined distance from the fourth switch contact of the second spring element. After the abrupt changeover, the contact between the first switch contact of the first spring element and the second switch contact of the second spring element is closed while the third switch contact of the third spring element and the fourth switch of the second spring element The contact between the contacts is open.

The locking lever according to claim 3 has a displacement lever for displacement from its blocking position. The displacement lever moves against the stopper at the start of the second switching stage. This design ensures extremely simple and inexpensive time switch manufacturing.

The arrangement of the stopper according to claim 4 and the shape of the displacement lever and its placement on the locking lever increase in displacement proportionally as the displacement of the switch lever increases with the switch contact of the spring element or the switching movement of the drum controller. To match each other. By this measure the exact switching point can be determined much more accurately. This means that if the rotational movement of the drum controller is constant, the displacement movement speed of the locking lever increases constantly until the end of the second switching stage. Thus, since the small rotational movement of the drum controller at the end of the switching step causes a large displacement of the locking lever, the switching timing can be set extremely precisely.

According to claim 5 the support shaft of the inherent switch lever is used as a stopper for the displacement lever of the locking lever. This reduces the number of parts of the time switch, thus enabling inexpensive manufacturing.

According to claim 6 a switch bar can be provided which is movable from the initial position to the first switching position. In the first switching position the switch lever is permanently fixed in that switching position. When the switch bar moves from its initial position to its first switching position, the switch lever simultaneously moves to its switching position. Thus, in the time switch according to the invention, the switch contacts of the two spring elements can simply be permanently contacted. This may be necessary, for example, when light is needed longer than inherent time switching in time controlled lighting. In addition, such switching is also necessary for the function of the consuming device to be tested in a short time, for example, without changing the time setting of the time switch.

According to claim 7, the switch bar can be moved to the second switching position. The second spring element of the second switch contact in the second switching position is such that the first spring of the first switch contact has a predetermined distance from each other even when the first spring element of the first switch contact is switched by the switch lever. Displacement with respect to the element. This enables a second permanent position of the time switch. That is, since the switch contacts are constantly opened, the connected consumer device may not be continuously operated. This may be necessary, for example, if the switching operation or closure of the switch contacts must be continually prevented, since the last consumer connected via the time switch according to the invention has to be repaired or replaced or is not needed, for example during a vacation.

According to claim 8 the translational movement of the switch bar for the displacement of the second spring element is transmitted to the second spring element by a lever mechanism. The lever mechanism allows the switch bar to be placed in the housing of the time switch to be extremely variable and easily accessible from the outside.

In summary, the design according to the invention of the time switch provides a time switch in which the switching time, ie the disconnection and closure of the switch contacts, can be set extremely precisely. In addition, two spring elements of the first switch contact and the second switch contact can be moved to two permanent switching positions. The permanent switching position enables two permanent switching, ie the continuous disconnection of the switch contacts and the continuous closure of the switch contacts.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 shows a time switch 1 according to the invention with its housing 2 open. The time switch 1 is used for example in an electrical switch cabinet due to the special shape of the housing 2. The drum controller 3 is rotatably supported by the housing 2. The drum controller is rotationally driven, for example by a synchronous motor 9, via a number of cogs 4, 5 and 6 and two worm gear pairs 7 and 8. Of course, other suitable motors rotating at constant speeds may also be used as the drive device. In this case, the speed ratio is selected such that the drum controller 3 makes a complete one turn of 360 ° C within 24 hours in the direction of the arrow 10 or within 7 days, for example in the case of a so-called weekly time switch. The drum controller 3 has a number of switch elements 11 and 12 around it. The switch elements 11 and 12 are provided for the operation of the switch lever 13. The switch elements 11 and 12 are adjustable in their radial position with respect to the drum controller 3 in this embodiment. That is, the switch element 11 with the outer surface element 14 lies radially outwardly than the switch element 12 with the surface element 15. The switch elements 11 and 12 thus form a stepped circumferential surface of the drum controller 3 in the circumferential direction. The stepped circumferential surface of the drum controller 3 is swept by a switch lever 13.

The switch lever 13 is rotatably supported on the pivot shaft 16. The pivot axis 16 extends parallel to the rotation axis 17 of the drum controller 3 and is arranged in the housing 2 of the time switch 1. The pivot shaft 16 of the switch lever 13 is arranged radially outward of the drum controller 3. As shown in FIG. 1, the switch lever 13 is formed of a double lever and includes a sensing section 18 and an operating section 19 opposite in diameter to the pivot axis 16. At the free end of the sensing section 18 a sensing finger 20 is provided. The sensing finger 20 extends laterally relative to the sensing section 18 and is formed of the switch elements 11 and 12 in the initial position of the switch lever 13 shown in FIG. 1 of the drum controller 3. It is inserted into the recess 21. Here, the sensing finger 20 is adjacent to the outer surface of the switch element 12 lying radially inward.

As shown in FIG. 1, a first spring element 22 and a second spring element 23 are arranged in the housing 2 of the time switch 1. The spring elements 22 and 23 comprise a first switch contact 24 or a second switch contact 25 in the region of the actuation section 19 of the switch lever 13. The two spring elements 22 and 23 are formed approximately in the form of leaf springs, as clearly shown in FIG. 1. The lower end of the first spring element 22, ie the end facing the switch contact 24, is fixedly arranged in the housing receptacle 27 together with the guide plate 26. The guide plate 26 is in electrical contact with the spring element 22. The spring element 22 supports the switch contact 24. A second housing receptacle 28 is provided laterally spaced with respect to the housing receptacle 27. The lower end of the second sppping element 23, ie the end facing the second switch contact 25, is received in the second housing receptacle 28 together with the second guide plate 29. The two guide plates 26 and 29 are guided to connecting terminals 30 or 31 which can be connected to the electricity consuming device.

Since the two switch contacts 24 and 25 are spaced from each other in the initial positions of the spring elements 22 and 23 shown in FIG. 1, they are not in electrical contact with each other. For this purpose, for example, a stopper 32 is provided in the housing 2. The stopper 32 prevents the second spring element 23 with the second switch contact 25 from being moved to the first spring element 22 with the first switch contact 24. A stopper 34 is provided on the rear face 33 of the first spring element 22 in approximately the region of the first switch contact 24. The stopper 34 is a constituent part of the free end of the operating section 19 of the switch lever 13.

The arrangement of the stopper 34 of the actuating section 19 in the initial position of the switch lever 13 shown in FIG. 1 is selected such that the safety clearance between the switch contacts 24 and 25 is assuredly ensured. As shown in FIG. 1, in this initial position of the switch lever 13 the spring element 22 is in the direction of the second spring element 23 by the stopper 34 of the operating section 19 under prestressing action. Slightly bent Thus, the first spring element 22 is adjacent to the stopper 34 without play. A locking lever 35 is provided on top of the first switch contact 24 at the upper end of the first spring element 22. A support peg 36 at the upper end of the locking lever 35 is rotatably supported in the support eye 37 of the spring element 22. In the end region opposite the support pegs 36 the locking lever 35 has a downwardly facing locking nose 38 extending laterally thereto.

The locking lever 35 forms a support surface 39 in front of the locking nose 38 at its free end, and is supported by the second spring element in a state in which the locking lever 35 is not loaded by the support surface 39. And slides on top edge 40 of 23. In order to ensure the initial position of the locking lever 35, a spring element may be provided which presses the support surface 39 of the locking lever 35 against the edge 40 of the second spring element 23. The spring element for the locking lever 35 is not shown in the figure for convenience.

As shown in FIG. 1, the locking lever 35 is provided with an upwardly facing displacement lever 41, which extends laterally with respect to the locking nose 38. The displacement lever 41 extends from the locking lever 35 past the pivot axis 16 of the switch lever 13. In the initial position shown in FIG. 1, the displacement lever 41 does not contact the pivot axis 16. The spacing between the stop face 42 of the locking nose 38 and the support pegs 36 is selected such that the stop face 42 does not contact the second spring element 23. Although the above dimensions of the locking lever 35 are not essential, the design allows the two spring elements 22 and 23 to take an initial position which is slightly prestressed as shown in FIG. 1.

The above-mentioned parts, namely the drum controller 3 with the switch elements 11 and 12, the switch lever 13, the two spring elements 22 with the two switch contacts 24 and 25 and ( 23, and by means of the locking lever 35 two spring elements 22, 23, and thus two switch contacts 24, for closing and opening the switch contacts 24, 25. Sudden relative movement of 25 is ensured as described in detail below. Due to this sudden switching movement caused by the locking lever 35 and the switch lever 13 interacting with the switch elements 11 and 12, it is precisely and electrically time-dependent as the drum controller 3 rotates. Perfect switching of switch contacts 24 and 25 is ensured.

For example, a switch bar 43 is provided for manual switching to ensure that switch contacts 24 and 25 are in constant or non-continuous contact. The switch bar 43 interacts with a displacement lever 44 of the switch lever 13 and a lever mechanism consisting of two reversing levers 45 and 46.

2 is an enlarged exploded perspective view of the individual parts belonging to the switch mechanism. 2 shows the upper ends of the spring elements 22 and 23, on the one hand a first switch contact 24 is arranged on the first spring element 22 and on the other hand a second switch contact 25. ) Is arranged on the second spring element 23. The spacing of switch contacts 24 and 25 shown in FIG. 2 corresponds to the spacing in the initial position of switch lever 13, shown in FIG. 1. At the upper end of the first spring element 22 a support eye 37 is arranged. The support eye 37 is formed of a bent spring section as an integral part of the first spring element 22. The first spring element 22 has a recess 47 in front of the support eye 37 in the axial direction. The recess 47 is used to receive the locking lever 35. As shown in FIG. 2, the support peg 36 of the locking lever 35 extends laterally relative to the locking lever 35, in particular with the small play as shown in FIG. 3 with the support of the spring element 22. It can be inserted into the eye 37. The locking nose 38 of the locking lever 35 is arranged in the end region facing the support pegs 36. The locking nose 38 protrudes from the locking lever 35 toward the bottom, approximately vertically. As already explained in FIG. 1, the supporting surface 39 is connected to the locking nose 38, by means of which the locking lever 35 is positioned at the initial position of the second spring element 23. It lies on top edge 40 (FIG. 3). A displacement lever 41 of the locking lever 35 is provided approximately on top of the locking nose 38. The displacement lever 41 is integrally formed with the locking lever 35 in this embodiment at approximately right angles to the locking lever 35 or at an angle greater than 90 °.

2 is a perspective view of the switch lever 13. The switch lever 13 has a hole 48 through which the switch lever 13 is pivotally supported on the pivot shaft 16. The pivot axis 16 is arranged on the rear wall 49 of the housing 2 of the time switch 1. The pivot shaft 16 may be formed directly on the rear wall 49 as an integral part or fixed to the rear wall 49 as a separate part. Sensing section 18 has sensing fingers 20 extending laterally relative to sensing section 18 at its free end. The function of the sensing finger 20 has already been briefly described in FIG. 1. As shown in FIG. 2, the operating section 19 of the switch lever 13 faces in diameter with the sensing section 18 with respect to the hole 48, and the axial direction of the axis of rotation 50 of the switch lever 13. Is disposed displaced relative to the sensing section by the width of the sensing section 18. The sensing section 18 and the operating section 19 are integrally coupled to each other. The displacement of the sensing section 18 and the actuating section 19 is selected such that the locking lever 35 extends to the sensing section 18 and is disposed next to the actuation section 19 in the axial direction. This results in an extremely small size of the lever device, in particular as shown in FIG. 3. The actuating section 19 also has a spring element side recess 51 towards its free end. The depth of the recess 51 is matched to the axial width of the support eye 37 of the spring element 22. At the end of the actuating section 19 is arranged a stopper 34 which is a component part of the reinforcing strip 52. In particular, as shown in FIG. 3, the axial length L of the stopper 34 and the reinforcing strip 52 is such that they have a front side edge 53 or 54 of the two spring elements 22 and 23. It is designed to lie together in one common plane. Thus, with the switch lever 13, the locking lever 35 with the displacement lever 41 and the device of the two spring elements 22 and 23 mounted, in particular as shown in FIG. The switch unit is formed. The switch unit forms an automatic part of the lever device of the time switch 1 according to the invention. That is, by means of the component, the locking lever 35 with its switch lever 13, the displacement lever 41 and its connection and the device of the two spring elements 22 and 23, the switch element 11 and The rotational position or rotation of the drum controller 3 with 12 causes automatic closure and opening of the two switch contacts 24 and 25.

For manual switching of the switch contacts 24 and 25 or their spring elements 22 and 23, the switch bar 43, the connecting lever 44 of the switch lever 13, as already described in FIG. 1. And two reversing levers 45 and 46. The switch bar 43 has an upper guide section 55, as shown in FIGS. 2 and 3 and 1. The guide section 55 guides the switch bar 43 axially movably between the guide strip 56 of the housing rear wall 49 and the top cover wall 57 of the housing 2. A locking peg 58 is provided in the rear end region of the guide strip 56. The locking pegs 58 protrude a guide strip 56 towards the switch bar 43 inwardly from the housing rear wall 49. The switch bar 43 has a locking bracket 59 disposed below the guide section 55. The locking bracket 59 extends approximately parallel to the guide section 55. The locking bracket has two locking strips 60 and 61 facing upwards in the region of its front end (right end in FIG. 1). The locking strips 60 and 61 are engaged in the locked state with the locking pegs 58 while the switch bar 43 is mounted. By means of two locking strips 60 and 61 and a locking peg 58 the intermediate initial position of the locking bar 43 in this embodiment is fixed, as shown in particular in FIGS. 1 and 3.

For operation of the switching bar 43, the switching bar 43 has an actuating lever 62 in its guide section 55. The actuation lever 62 protrudes from the outside through a corresponding through opening 63 (FIGS. 1 and 4) of the upper cover wall 57 of the housing 2 of the time switch 1 in the mounted state. do. The size of the through hole 63 is matched such that the switch bar 43 is moved from its initial position shown in FIGS. 1 and 3 to two switching positions which are transposed oppositely, as described in detail below. . That is, the through hole 63 forms a stopper for the actuating lever 62 and thus the entire switch bar 43 for the two switching positions.

In the switching position moved in the direction of the arrow 64 from the initial position, the guide section 55 is operatively connected with the front end of the switch bar 43, whereby the switch lever 13 is actuated. For this purpose, the switch lever 13 has a switch peg 66 extending parallel to the axis of rotation 50 at its connecting lever 44. Through the switch pegs 66 the connecting lever 44 and thus the entire switch lever 13 is actuated in the direction of the arrow 64 by the front end 65 of the switch bar 43. In this switching position, the continuous closure of the two switch contacts 24 and 25 is caused as described in detail with respect to FIG. 8 below.

In contrast, when the switch bar 43 is moved in the opposite direction to the arrow 64, the switch bar is operatively connected to the reversing lever 45. For this purpose, the switch bar 43 comprises a switch nose 67 in its guide section 55 downward in the region of its front end 65. The switch nose 67 is operatively connected with the adjustment lever 68 of the upper reversing lever 45 towards the switch bar 43 when the switch bar 43 is retracted as opposed to the arrow 64. The reversing lever 45 has a support hub 70 rotatably supported on a larger diameter support section 69 of the pivot axis 16 and thus with a through hole 71. A second lever arm 72 is provided on the support hub 70 of the reversing lever 45 on the side opposite to the adjustment lever 68. The lever arm 72 has a hole 73 extending radially from the support hub 70.

As shown in FIG. 2, the housing rear wall 49 has an additional support peg 74 approximately below the pivot axis 16 or the support section 69. A second reversing lever 46 with a support hub 76 with a support hole 75 is rotatably supported on the support peg 74. The reversing lever 46 has a first adjustment lever 77 on its support hub 76 that faces towards the first reversing lever 45. The adjustment lever 77 has an insertion peg 79 parallel to the rotational axis 78 of the reversing lever 46. The insertion pegs 79 engage with the holes 73 of the lever arm 72 of the first reversing lever 45.

An actuating lever 80 is disposed on the support hub 76 of the second reversing lever 46 on the side facing the first adjusting lever 77. The actuating lever 80 is an integral part of the reversing lever 46 and is displaced forward in the axial direction of the rotary shaft 78. In the mounted state, as shown in FIG. 3, the actuating lever 80 lies in approximately the same vertical plane as the adjusting lever 68 of the second lever arm 72 and the first reversing lever 45. By this design, a configuration requiring an extremely small place is achieved.

The actuation lever 80 has an adjustment peg 81 at its outer end. The adjusting pegs 81 are used for the adjustment of the second spring element 23 with the second switch contact 25 when the reversing lever 46 pivots.

4 shows a perspective view of the complete switch mechanism of the time switch 1 according to the invention in the fitted state. In the switching position shown, the switch elements 11 and 12 of the drum controller 3 are arranged so that the switch element 12 which does not switch radially inwardly is in the sensing finger 20 area of the switch lever 13. It is placed in a rotational position lying on. In the initial position corresponding to the initial position of FIG. 1, the two switch contacts 24 and 25 are spaced from each other, so that no electrical connection is made between the two components. The first spring element 22 is outwardly adjacent to the stopper 34 of the switch lever 13 or its operating section 19. The support surface 39 of the locking lever 35 rotatably supported by the support eye 37 of the spring element 22 lies on the upper edge 40 of the second spring element 23. In addition, since the second spring element 23 is adjacent to the stopper 34, the second spring element 23 cannot be moved to the first spring element 22. An adjusting peg 81 of the lower reversing lever 46 is arranged between the two spring elements 22 and 23. The adjusting pegs 81 have a minimum spacing with respect to the inner surface 82 of the second spring element 23 in the shown switching position, so that the second spring element 23 is secured to the stopper 32 at the predetermined position. Adjacent to each other. In addition, the locking nose 38 of the locking lever 35 also has a constant distance with respect to the second spring element 23. Thus, the relative position of the two spring elements 22 and 23 in the shown switching position is determined by the initial position of the switch lever 13 or its stopper 34 and by the fixed position of the stopper 32. . In this position, the displacement lever 41 has a constant spacing with respect to the pivot axis 16 of the switch lever 13, so that the fixed initial of the two spring elements 22 and 23 by the locking lever 35 is established. The location is not affected. In addition, as shown in FIG. 4, the displacement lever 41 of the locking lever 35 lies in approximately the same vertical plane as the sensing section 18 of the switch lever 13. The operating section 19 of the switch lever 13 extends behind the sensing section 18 and behind the locking lever 35 in the axial direction of the rotary shaft 50 of the switch lever 13, while its reinforcing strip 52. Is engaged with the stopper 34 behind the first spring element 22. The arrangement of the two spring elements 22 and 23 and the locking lever 35 and the sensing section 18 are chosen such that their front boundary or boundary edges lie in at least approximately one common vertical plane.

In the initial position shown, the switch peg 66 of the connecting lever 44, which is arranged approximately perpendicular to the sensing section 18 and the actuating section 19, is the top of the switch bar 43 in the vertical and horizontal directions. It is disposed immediately near the front end edge 83 of the guide section 55. Since the two locking strips 60 and 61 of the switch bar 43 are positively engaged with the locking pegs 58 of the guide strip 56, the neutral initial position of the switch bar 43 is fixed. That is, in the neutral switching position of the switch bar 43, the switch bar 4 has a switching lever 13 in which the drum controller 3 interacts in the direction of the arrow 10 and thus with the locking lever 35. There is no effect on automatic switching during rotation in the direction of the switching action of the two spring elements 22 and 23. Due to the neutral position of the switch bar 43, the two reversing levers 45 and 46 are placed in a neutral position, ie in a position where they may not affect the automatic switching operation.

As clearly shown in FIG. 4, the switching mechanism of the automatic component consisting of the switch lever 13 and the locking lever 35 and the passive component consisting of the switch bar 43 and the two reversing levers 45 and 46 Since a very compact and slim unit is formed, the time switch 1 has a very slim configuration as a whole.

5, 6 and 7 show the individual switching steps for the automatic switching of two switch contacts 24 and 25 via spring elements 22 and 23.

At the start of the first switching stage, the radially outwardly active switch element 11 of the drum controller 3 is placed at a constant rotational angle position. Viewed in the rotational direction at the rotational angle position, the front switch element 11 is directly adjacent the adjustment surface 84 which forms the inclined surface of the sensing finger 20 at the rear. The switch element in which the switch lever 13 with the sensing section 18 and the operating section 19 is in its initial position, ie the sensing finger 20 is in the inactive switching position at the start of the first switching phase. It is arrange | positioned at the position which contacts 12 from an outer side surface. As already explained in FIGS. 1 and 4, the stopper 34 of the actuating section 19 of the switch lever 13 under the slight prestressing action of the spring element 22 in the initial position of the switch lever 13. Adjacent to. At the same time, the second spring element 23 is adjacent to the stopper 32 under prestressing action. In this position, a secure distance between the two switch contacts 24 and 25 is ensured. The support surface 39 of the locking lever 35 rests on the upper edge 40 of the second spring element 23, the locking nose 38 of which is arranged a predetermined distance relative to the second spring element 23. Have Similarly, at least a small gap is also provided between the displacement lever 41 of the locking lever 35 and the pivot shaft 16 disposed below the switch lever 13 in the initial position.

As shown in FIG. 5, since the sensing section 18 of the switch lever 13 is omitted toward the displacement lever 41 in the region of the support hole 48, the displacement lever 41 of the locking lever 35 in the switching operation. Is directly supported on the pivot axis 16 and slides along the pivot axis 16. This makes the switching operation unaffected by the manufacturing tolerances of the switch lever 13 or its sensing section 18 and a very accurate switching time can be set.

During further operation, the switch elements 11 and 12 of the drum controller 3 rotate in the direction of the arrow 10 from the rotational position shown in FIG. 5, so that the sensing finger 20 of the switch lever 13 Displaced radially outward along the frontmost active switch element 11 via the adjustment surface 84, so that the switch lever 13 rotates about the pivot axis 16 in the direction of the arrow 85. Simultaneously with the rotation of the switch lever 13, the sensing section 18 and the actuating section 19 opposite to it rotate with the stopper 34 about the pivot axis 16 in the same direction. The rotation causes the spring element 22 to be displaced to the second spring element 23 in the direction of the arrow 86. Since the locking lever 35 is supported in the support eye 37 of the first spring element 22, the locking nose 38 of the locking lever 35 also has a second spring element 23 in the direction of the arrow 86. Is moved to the upper end of. The displacement lever 41 of the locking lever 35 is also moved in the direction of the arrow 86 until the turning peg side front adjustment surface 87 contacts the turning peg 16 of the switch lever 13. If the drum controller 3 continues to rotate in the direction of the arrow 10, the switch lever 13 is further displaced, so that the first spring element 22 is further displaced in the direction of the arrow 86, and the locking moves together. Since the lever 35 is rotated in the direction of the arrow 88 in the support eye 37 of the spring element 22 by its displacement lever 41 on the pivot axis, the support surface 39 of the locking lever 35 This is gradually separated from the upper edge 40 of the second spring element 23.

6 shows the switching position just before the end of the first switching stage. In this switching position the locking nose 38 of the locking lever 35 engages with the second spring element 23. As shown in FIG. 6, the first spring element 22 and the second by the locking lever 35 and by the spacing between the locking nose 38 and the support eye 37 of the first spring element 22. The upper end of the spring element 23 is maintained at a predetermined interval. The gap is designed in such a size that the two switch contacts 24 and 25 are not surely in electrical contact with each other until the end of the first switching stage. Thus, the two switch contacts 24 and 25 have a gap shown in FIG. 6, which is scheduled by at least the locking lever 35 from each other during the entire first switching value step. The rotation of the locking lever 35 in the direction of the arrow 88 is made along the pivot axis 16 of the switch lever 13 by sliding the displacement lever 41 as described above, while the first spring element 22 ) Is further displaced in the direction of the arrow 86 through the stopper 34 of the operating section 19 of the switch lever 13. At the same time, the spring element 23 is also moved together in the direction of the arrow 86 due to the positive engagement of the locking nose 38 of the locking lever 35 at the spring element 23 until the end of the first switching stage.

The second exercise step is followed by the end of the first exercise step shown in FIG. 6. The end of the second movement phase is shown in FIG. As shown in FIG. 7, the drum controller 3 remains until the sensing finger 20 of the switch lever 13 or its sensing section 18 rests on the outer circumferential surface 89 of the switch element 11. , Is further moved in the direction of the arrow 10. While moving from the position of the switch lever 13 shown in FIG. 6 to the position shown in FIG. 7, the switch lever 13 is further rotated in the direction of the arrow 85, whereby the stopper 34 of the operating section 19. ), The spring element 22 is further moved in the direction of the arrow 86. The locking lever 35 is moved in the direction of the arrow 86 through the supporting eye 37 of the spring element 22, so that the locking lever 35 is adjacent to the displacement lever 41, that is, the pivot axis 16, and the pivot axis 16. Since the displacement lever 41 which slides upward in the direction of the arrow 90 upwardly is moved, the locking lever 35 is further rotated in the rotational direction of the arrow 88. Thus, immediately after the position shown in FIG. 6, the locking nose 38 of the locking lever 35 releases the switch contact 25 of the spring element 23 which is under prestressing action, so that the spring element 23 is sudden. Smoothly moved to the first switch contact 24 in the direction of the arrow 91, ie in the closed direction, and in electrical contact with the contact. When the drum controller 3 is further rotated in the direction of the arrow 10 until the sensing finger 20 reaches the area of the switch element 12 which is radially inward, the sensing finger 20 moves in the radial direction. After passing through the last edge 105 of the last switch element 11 on the outside, it suddenly returns to the initial position shown in FIG. 5. At the same time, since the first spring element 22 is likewise released by the stopper 34 which has been moved back to the initial position shown in FIG. 5, the locking lever 35 likewise returns to the initial position shown in FIG. 5. At the same time, since the second spring element 23 also returns to the initial position of FIG. 5 again and is adjacent to the stopper 32, the two switch contacts 24 and 25 suddenly move the sensing finger 20 and accordingly Sudden relocation of the entire switch lever 13 causes a sudden separation back in the opposite direction of the arrow 85.

Due to the aforementioned lever mechanism of the locking lever 35 with the switch lever 13 on the one hand and the displacement lever 41 on the other hand, for the closing of the switch contacts 24 and 25 and two switches The switching point for the separation of contacts 24 and 25 can be clearly determined.

In addition, due to this particular configuration, for example, as shown in FIGS. 8 and 9, two continuous switching of the switch contacts 24, 25 of the two spring elements 22, 23, i. Position or a continuously open switching position is possible. The switch bar 43 can now be moved by its actuating lever 62 from the basic position of FIG. 5 to the position shown in FIG. 8 in the direction of the arrow 92. As shown in FIG. 5, the switch peg 66 of the displacement lever 44 is disposed at an initial position above the lower adjustment surface 93 of the guide section 55 of the switch bar 43. By moving the switch bar 43 in the direction of the arrow 92, the switch peg 66, together with its connecting lever 44, is moved from the position shown in FIG. 5 to the switching position shown in FIG. 8. Thus, the whole switch lever 13 rotates together with the connecting lever 44 and the operating section 19 of the switch lever 13 again in the direction of the arrow 85 about the pivot axis 16. When the stopper 34 disposed at the end of the operating section 19 is further moved in the direction of the arrow 86 by the horizontal component, the first spring element 22 is also pressed in the direction of the arrow 86. During this movement, the locking lever 35 makes the same rotational movement in the direction of the arrow 88 about the support eye 37, as already described in FIGS. 5, 6 and 7. That is, the locking lever 35 reliably releases the upper end of the second spring element 23 in its end position as shown in FIG. 8, so that the spring element has its second switch contact due to its elastic prestress. Electrical contact with the first switch contact 25 of the first spring element 22. Thus, the two switch contacts 24 and 25 are closed. As shown in FIG. 8, in the fixed end position of the switch lever 13, at least in the direction of the arrow 85, for safety reasons, corresponding to at least the final turning position of the switch lever 13 in FIG. 7. The pivot position, which is further moved by degrees, is fixed.

In the position shown in FIG. 8, the actuating lever 62 of the switch bar 43 is moved up to the stopper 94 of the through hole 63 of the upper cover wall 57. In this position, the switch bar 43 is secured by the locking strip 60 in the locking pegs 58 of the guide strip 56. In the switching position shown in FIG. 8 of the switch lever 13 together with the spring elements 22, 23 and the associated switch contacts 24, 25 in contact, two switch contacts 24 and 25. Permanent contact between) is made according to each position of the drum controller 3 shown in phantom lines. By this design of the time switch, the two switch contacts 24 and 25 can be brought into a fixedly connected switching position.

In order to ensure a fixed blocked position of the two switch contacts 24 and 25, two reversing levers 45 and 46 are provided as shown in FIG. Since the switch bar 45 is moved again in the direction of the arrow 95 from the initial position of FIG. 5, the locking strip 61 of the switch bar 45 is locked to the locking pegs 58 and the switch bar 45 Is adjacent to the second stopper 96 of the through hole 63 of the upper cover wall 57. In this position, the switch bar 43 is secured by the locking strip 61 in the locking pegs 58, as shown in FIG. As already explained in FIGS. 2 and 3, a switch nose 67 is provided on the lower adjustment surface 93 of the guide section 55 of the switch bar 43. In adjustment of the switch bar 43 in the direction of the arrow 95, the switch nose 67 interacts with the adjustment lever 68 of the reversing lever 45 and this supports the supporting section 69 of the pivoting pegs 16. Rotate in the direction of the arrow 97 around. By the adjustment movement of the reversing lever 45 at the same time the second reversing lever 46 is in the opposite direction of rotation about the support peg 74 due to its mechanical coupling through the insertion peg 79 with the hole 73. Is turned 98. By the rotation in the rotational direction of the arrow 98, the adjustment peg 81 makes an adjustment movement by the horizontal component in the direction of the arrow 99 at the lower end of the actuating lever 80 of the reversing lever 46, The second spring element 23 is also displaced in this direction. However, since the first spring element 22 is not affected by the adjustment movement, the spacing between the two switch contacts 24 and 25 causes the switch bar 43 and the reversing levers 45 and 46 to fail. Becomes very large at the second switching position. The adjustment movement in the direction of the arrow 99 is due to the shift ratio of the switch bar 43 and the two reversing levers 45, 46, so that the first switch contact 24 is activated by the first spring element 22. The switching is selected such that it is not surely contacted with the switch contact 25 as shown in FIG. 7.

Due to the embodiment of the invention according to FIGS. 8 and 9, two extreme positions or switching positions can be permanently set by the switching mechanism according to the invention. That is, on the one hand, the switch contacts 24 and 25 can be continuously closed according to the embodiment of FIG. 8. Likewise, the contacts 24 and 25 are reliably continuously opened in the second switching position of the switch bar 43 according to FIG. 9.

FIG. 10 shows an embodiment with a locking lever 35/1 which is an integral part of the first spring element 22/1. At the upper end a first switch contact 24/1 is provided to the first spring element 22/1. The switch contact is a predetermined spacing for the second switch contact 25/1 disposed on the second spring element 23/1 at the shown initial position of the spring element 22/1 and the spring element 23/1. Is placed. The locking lever 35/1 is formed integrally with the first spring element 22/1 above the spring section 100 formed in an approximately ring shape on top of the first switch contact 24/1. In the initial position shown, the locking lever 35/1 extends substantially perpendicular to the first spring element 22/1, bent downwardly at a substantially right angle and bent toward the second spring element 23/1. (38/1) An electrically insulating stopper 101 is provided at the upper end of the second spring element 23/1. The stopper 101 is for example made of plastic and can be injection molded, for example, on the upper end of the second spring element 23/1. Since the horizontal spacing of the locking nose 38/1 with respect to the stopper 101 is selected to be smaller than the spacing between the two switch contacts 24/1 and 25/1, the first spring in the direction of the arrow 102. Upon displacement of the element 22/1, when the locking nose 38/1 engages with the stopper 101, the two switch contacts 24/1 and 25/1 are spaced apart from each other with certain electrical conduction. Are kept together. The other function corresponds to the embodiment of the locking lever 35 described in Figs. The actuation of the first spring element 22/1 is likewise made by a switch lever 13 or its stopper 34 at the end of the actuation section 19. For the displacement of the locking lever 35/1, the locking lever 35/1 also has a displacement lever 41/1 formed integrally therewith. Also in the embodiment of FIG. 10, the locking lever 35/1 is retracted by a certain distance in the direction of the arrow 102 and then displaced upward in the direction of the arrow 103, so that the second spring element 23 during the second switching step. / 1) is released abruptly as well. In order for the locking nose 38/1 of the locking lever 35/1 to be locked to the stopper 101 during the retraction movement in the direction opposite to the direction of the arrow 102, the rear surface of the stopper 101 is inclined to the displacement surface 104. ), The locking lever 35/1 can be reliably retracted to the initial position shown in FIG. In order to fix the initial position of the second spring element 23/1, a stopper 32 is also provided. The stopper 32 is fixedly arranged in a time switch housing not shown in FIG.

11 shows another embodiment of the support of the locking lever 35/2 against the first spring element 22/2. The locking lever 35/2 may be formed of, for example, a metal material or plastic; In the first case, an electrically insulating stopper should likewise be provided to the second spring element (not shown in the figure) according to the embodiment of FIG. 10. In order to pivotally support the locking lever 35/2 to the first spring element 22/2, the first spring element 22/2 has two side edges 106 and 107 at its upper end. It has two support slots 108 and 109 in the region of. Two support brackets 110 or 111, which are arranged on the locking lever 35/2 at corresponding intervals, are inserted through the slots. Since the two support brackets 110 and 111 are bent upwardly vertically at the rear face in this embodiment, the locking lever 35/2, which extends between the two support brackets 110 and 111, The support edge 112 is adjacent to the front face of the spring element 22/2 and can be displaced upwards about the support edge 112. The other design of the locking lever 35/2 may be the same as that of the locking lever 35/1 of FIG.

Another embodiment is also possible for the support of the locking lever against the first spring element. It is only important that the locking lever can be displaced in this direction, for example as indicated by arrow 103 pointing upwards vertically in FIG. 10. For the reset of the locking lever, a spring element, not shown in the figure, may be provided. The spring element can be arranged in the housing of the locking lever, the spring element or the time switch and push each locking lever in the opposite direction to the arrow 103 by the force of the spring. The locking lever itself or, in particular, as shown in the embodiment of FIG. 10, may be elastically formed in engagement with the first spring element. In addition, the locking lever is movably supported in the direction of the arrow 102 of FIG. 10 in the corresponding guide in the housing, the displacement being arranged on one or both sides of the locking lever by the corresponding design of the guide slot in the housing. It is caused by the connecting link guide way through the guide peg inserted into the guide slot. Also, as shown in the embodiment of FIG. 10, in all cases an electrically conductive connection via the locking lever cannot occur between the first spring element and the second spring element. This can be done on the one hand by the selection of the material of the locking lever itself or on the other hand by additional insulation measures in the locking lever or the spring element.

12 and 13 show an embodiment of a switch contact device formed of so-called switching contacts.

The switching device is provided with a first spring element 22/3 and a second spring element 23/3 corresponding to the spring elements 22 and 23 of the embodiment of FIGS. 5 to 9. At the upper end of each spring element 22/3, 23/3, a first switch contact 24/3 or a second switch contact 25/3 is arranged. The switch contacts have a predetermined distance from each other in the initial position shown in FIG. To make this predetermined spacing, the first spring element 22/3 is adjacent to the stopper 34/3 under prestressing action at the initial position shown therein according to the embodiment of FIG. 5. The side of the stopper 34/3 is arranged at the outer end of the operating section 19/3 of the switch bar 13/3. The switch bar 13/3 is rotatably supported about the pivot axis 16. In addition, since the second spring element 23/3 is fixed to the initial position shown in FIG. 12 by the stopper 32, the two switch contacts 24/3, 25/3 are intended to be mutually predetermined, i.e. electrical There is an interval at which no connection is made. In addition to the two spring elements 22/3 and 23/3, a third spring element 113 with a third switch contact 114 is provided. The third switch contact is in permanent electrical connection with the fourth switch contact 115 of the second spring element 23/3. The fourth switch contact 115 is disposed opposite the second switch contact 25/3 at the second spring element 23/3. An additional guide plate according to the manner of the two guide plates 26 and 29 of FIG. 1 can be provided for the spring element 113. The side surface of the guide plate is connected to the third connecting terminal (not shown in the figure). Since the third spring element 113 is prestressed, its switch contact 114 is likewise adjacent to the fourth switch contact 115 under the prestressing action and thus the fourth switch contact at the initial position shown in FIG. 12. It cannot be inadvertently separated from 115. "Conversion contacts formed of three spring elements 22/3, 23/3, 113 and its four switch contacts 24/3, 25/3, 114, 115 For switching, "a locking lever 35/3 with a locking nose 38/3 is provided. The locking nose 38/3 corresponds to the locking nose 38 of the switch lever 35 of FIGS. 5 to 7 in design and function. An upwardly supporting surface 39/3 is connected to the locking nose 38/3 forwards in the direction of the arrow 102.

In addition, a vertically downward switch finger 116 is provided at intervals with respect to the locking nose 38/3. In this embodiment, the vertically downward length of the switch finger 116 is formed much longer than the locking nose 38/3. A displacement lever 41/3 is disposed approximately above the switch finger 116. The function of the displacement lever 41/3 corresponds to the function of the displacement lever 41 of the embodiment of FIGS. 5 to 7.

Thus, when the switch elements 11 and 12 of the drum controller 3 shown in phantom lines rotate in the direction of the arrow 10 from the initial position shown in Fig. 12, the switch lever 13/3 turns. The pivoting motion is performed in the direction of the arrow 85. The stopper 34 displaces the spring element 22/3 in the direction of the horizontal arrow 102 until the locking nose 38/3 engages with the second spring element 23/3. In this position the switch fingers 116 are at regular intervals with respect to the third spring element 113 in the horizontal direction so that the two switch contacts 114 and 115 are in fixed contact. In addition, a locking nose 38/3 is arranged in the locking lever 35/3 so that the two switch contacts 24/3 and 25/3 are kept at predetermined intervals from each other during the first switching step. At the end of the first switching step, the turning lever 41/3 of the locking lever 35/3 contacts the pivot axis 16 of the switch lever 13/3 and turns arrow at the beginning of the second switching step following it. It starts to pivot about its support axis in the direction of 88. Even in this state, since the safety gap is maintained between the switch finger 116 and the third spring element 113, the two switch contacts 114 and 115 are in electrical contact with each other.

By continuing to turn the switch lever 13/3 to the end position shown in FIG. 13 in the direction of the turning arrow 85, the second spring element 23/3 is connected to the two switch contacts 25/3 and 115. Is suddenly locked to the locking nose 38/3, because during this pivoting movement of the switch lever 13/3 the locking lever 35/3 is further rotated in the direction of the turning arrow 88 , Corresponding turning movement of the locking nose 38/3 and the switch finger 116 in the direction of the approximately vertical arrow 103 is caused. As shown in FIG. 13, the third spring element 113 is adjacent to the lower end of the switch finger 116 after the locking of the second spring element 23/3 to the locking nose 38/3 is released. Is fixed to the fixed position shown in FIG. Since the spring element 23/3 is suddenly released from the locking nose 38/3, the contact between the two switch contacts 114 and 115 is also suddenly opened, while at a later point in time immediately after The two switch contacts 25/3 and 24/3 are suddenly closed.

Thus, by the switching device according to the embodiment of FIGS. 12 and 13, the switching from the first consuming device to the second consuming device can be made abruptly. For example, the first consumer device is in electrical contact with a connection terminal associated with the first spring element 22/3 with the switch contact 24/3 while the second consumer device has a third spring with the switch contact 114. Pertains to element 113. The restoring motion of the spring elements 22/3, 23/3, and 113 from its end position shown in FIG. 13 to the initial position shown in FIG. 12 is already described in FIGS. When the lever 13/3 reaches the operating range of the inactive switch element 12, the switch lever 13/3 suddenly returns to the initial position of FIG. 12 in the opposite direction to the direction of the arrow 85. In a sudden way.

Thus, in summary, on the one hand the correct automatic switching of switch contacts 24 and 25 can optionally be set by means of a time switch according to the invention. The closing of the switch contacts 24, 25 takes place abruptly as the locking lever 35 is released from the second spring element 23. This sudden opening of the switch contacts 24, 25 is abruptly into the free space of the drum controller 3 which is given by the switch element 12 in which the switch nose 20 of the switch lever 13 is inactive. By inserting it smoothly. The same applies to the embodiment according to FIGS. 10 to 13.
