Definitions
- the invention relates to a timer with at least one first and a second elastic spring element, each are provided with at least one switching contact, and with a rotationally driven shift drum that has several with respect to a rotatably mounted shift lever in each case either in an effective or ineffective switch position
- Has adjustable switching elements through which the Shift lever from an inactive starting position to a rotating Switch position is deflected and the first spring element with its switching contact to carry out a switching operation with the switching contact of the second spring element brings in contact, and with further rotation of the Shift drum of the shift lever for sudden separation of the Switch contacts suddenly return to their starting position.
- DE 27 54 212 B1 is a time switch of the generic type Kind known, which at least a first and a has second switching contact, which on a first and a second, elastic approximately leaf spring-like spring element anorg.sind.
- This time switch is used as a shift drum a double switch star that can be driven in one direction of rotation provided the two coaxial, by half a tooth pitch has shift sprockets offset from one another.
- This Gear rims are provided with ratchet teeth, each for one or more spring elements of the switch contacts Operate a switching operation suddenly.
- Time switches have become known, such as from DE 28 13 069 C2, in which a shift drum is used.
- the shift drum is provided with shifting elements that are made of an effective position switchable to an ineffective position are. In the effective position, the Switching elements during the rotation of the shift drum Shift lever operated, which in turn one Microswitch activated.
- the number of adjustable Accordingly, switching times are only based on the number the switching elements arranged on the circumference of the shift drum dependent. The greater this number of switching elements, the more the switching distances between the individual are smaller Switching operations adjustable.
- the shift lever is on this one known time switch designed as a double-armed scanning lever, which by a spring against a switching plunger of the Microswitch is held.
- the scanning lever against a spring force from an initial position deflected into a switching position so that the microswitch is actuated via its switching plunger.
- the sensing lever suddenly falls back into his Starting position back so that the microswitch at this switching operation is suddenly opened again or is switched to its initial position.
- the shift drum runs the scanning lever with a Switch nose again against an actively switched switching element and is relatively slow in starting from its shift position deflected.
- the disadvantage here is that the microswitch during this extremely slow movement of the Shift lever is also operated extremely slowly, so that its switching position or switching time is only extremely is imprecise.
- Snap switch become known (DE 38 25 308 A1), which work according to the principle of deadlock.
- These switches are provided with a rocker switch, which by the shift lever is switched. Because the one switching direction of the shift lever done suddenly by the shift lever itself, if this falls back into its starting position, it is Switch position can be predetermined quite precisely.
- Opening of the shift lever on an actively switched Switching element is the time at which the rocker switch suddenly from her inactive position to her active one Position switched, cannot be determined exactly. Therefore have switching devices with such snap switches adjustment devices with which the exact switching time must be set.
- the invention has for its object a To improve the time switch of the generic type in such a way that using elastic spring elements with switch contacts, both variably adjustable switching times as also a precise setting option for both switching operations or switching times, i.e. both when turning on as well as when switching off the electrical switch are.
- a Locking lever is provided, which during the closing process by the first spring element actuated by the shift lever is moved in the direction of the second spring element, and that the locking lever during a first switching phase of Closing process in a locked position by a latch positively engaged with the second spring element stands and the two spring elements with their switching contacts biased at a predetermined distance from each other holds, and that the locking lever during a second, switching phase following the first switching phase from its locked position by at least with the locking lever actively connected during the second switching phase Deflection element is deflected and the second spring element of the second switching contact for the sudden Closing the switch contacts suddenly releases.
- a locking lever is provided, which during the closing process by the one operated by the gear lever first spring element in the direction of the second spring element is moved.
- this closing movement of the first spring element stands Locking lever via a locking lug with the second spring element in a positive connection, so that the second spring element with its switching contact in a predetermined Distance to the switching contact of the first spring element kept becomes. That that the locking lever during this first Switching phase of the closing process is in a locked position and by means of the locking lug with the second Spring element is engaged.
- the two spring elements are with their switching contacts under tension in the predetermined distance from each other.
- this locking lever is arranged so that it is in a locked position in the first switching phase, in which the two spring elements with their switching contacts by the locking lever under prestress in the predetermined Be kept apart.
- the locking lever stands with the first spring element of the second switching contact latching into engagement.
- the shift lever is activated by a switching element the rotationally driven shift drum due to the extremely low rotation per unit time of the shift drum deflected extremely slowly. This deflection will first spring element of the first switching contact through the Shift lever in the direction of the second spring element of the second switching contact moves slowly.
- the two switch contacts of the first spring element and the second spring element but can due to the between the spring elements locking lever lying in the locked position do not come into contact with each other.
- both spring elements are under a certain spring elastic preload.
- the locking lever increases with increasing Adjustment movement of the spring elements from its locked position deflected.
- the Locking lever the second spring element of the second switching contact free, so that the switching contacts suddenly conclude.
- the locking lever is deflected via a deflection element, which, depending on the arrangement and storage of the Locking lever, for example a fixed adjusting pin or can also be a kind of ramp, along which or which the locking lever during the second switching phase of the closing movement slides open.
- the actual one in such time switches Shift lever on a touch finger, which on the peripheral surface of the shift drum.
- the switching elements of a such shift drum steer this switching nose radially Shift drum outwards, see above. that the gear lever one Performs pivoting movement through which the switching process the spring elements with their switching contacts is effected.
- the deflection is usually extremely slow because the Switch nose forms a kind of ramp with which it leads to it Deflection along an active switching element during the slow rotation of the shift drum outwards slides.
- this active switching position remains of the shift lever until the last active switching element on the switching nose of the shift lever has moved past.
- the Switching times for switching on and off i.e. to the Closing or for disconnecting the switch contacts, extremely precise be predetermined. There may be additional ones in particular Adjustment devices for determining these switching times to be dispensed with. Because of the quick closing and Opening the switch contacts is also a considerable less erosion of the switching contacts themselves achieved. Also can by interpreting the strength of the spring elements or the elasticity of these spring elements also the switching forces or the contact forces between the switch contacts can be clearly determined in a simple manner, so that a optimal contact closure is always guaranteed.

- This is the first and second spring element a third spring element with a third switch contact assigned that with its switching contact as long as one fourth switching contact arranged on the second spring element is in permanent electrical contact until the second Spring element from the locking lever during the second switching phase is suddenly released.
- the Provide locking lever with a shift finger through which the third spring element after the sudden release of the second spring element with its third switch contact in a predetermined distance from the fourth switching contact of the second spring element is held. After this sudden Switching process is thus the contact between the first switching contact of the first spring element and the second switching contact of the second spring element closed, during the contact between the third switch contact of the third spring element and the fourth switching contact of the second spring element is open.
- the locking lever for deflecting it provide its locking position with a lever, which against a stop at the beginning of the second switching phase running.
- the arrangement of the stop and the shape and the arrangement of the deflection lever on the locking lever matched to each other so that the deflection of the Shift lever with increasing switching movement of the spring elements disproportionate with their switching contacts or the shift drum increases.
- This measure can also be used determine the precise switching point much more precisely. This means that the speed of the deflection movement the locking lever with constant rotation of the shift drum increases steadily towards the end of the second switching phase. Consequently causes a slight rotation of the shift drum at the end the switching phase a large deflection of the locking lever, so that the switching time can be set extremely precisely.
- a slide switch can be provided which from an initial position to a first switching position can be brought.
- the shift lever In this first switch position the shift lever is permanently in its shift position fixed.

- such a circuit is also necessary to temporarily function as a To be able to test the consumer without changing the time setting the time switch must be changed.
- the slide switch is in a second Switchable position in which the second spring element of the second switching contact relative to the first spring element of the first switching contact is deflected that the switch contacts even when switched by the shift lever a first spring element of the first switching contact have a predetermined distance from each other.
- This will allows a second permanent position of the timer. that is, that the switch contacts are constantly open and a connected one Consumers are therefore permanently shut down can be. This may be necessary, for example be when a switching operation or a closing of the switching contacts should be prevented in the long run because of the over the time switch switched end consumer needs to be repaired or replaced or for example is not needed on vacation.
- the translational switching movement of the slide switch for deflecting the second spring element through a lever mechanism on the second spring element transfer With this lever mechanism, the slide switch can extremely variable, easily accessible from the outside in the housing the time switch can be arranged.
- the configuration according to the invention provided the time switch with a time switch, at which the switching times, i.e. separating and closing of the switching contacts can be set extremely precisely.
