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

The timing switch that has electric opening/closing device

Technical field

The present invention relates to a kind of timing switch.

Background technology

By the timing switch of known a kind of this type of DE 27 54 212 B1, it has at least one first and second switch contact, they be arranged on one first with one the second flexible spring element that roughly becomes leaf spring shape on.Be provided with a dual rotary type switch that can drive to direction of rotation as the switch drum in this timing switch, it has two concentric, stagger switching ring gears of half tooth distance mutually.These gear rings are provided with the locking tooth, and they are one or several spring element of great-jump-forward ground master cock contact separately, to realize switching process.Just reach switching time as far as possible accurately in order not do any adjustment work, respectively the waiting to handle and be provided with switch lever between the spring element of switching ring gear and switch contact, they are separately by in one in the switching ring gear of a dual rotary type switch of direction locking boss embedding that generates on switch lever respectively.By the switching ring gear switch lever alternately or deflection in turn successively and falling, after the locking tooth of each switching ring gear nuzzles up the direction locking boss that respectively sets of a plurality of switch levers, get back to its original position to great-jump-forward or impact type, cause the switching process of a kind of great-jump-forward or impact type thus.

With determining by the quantity of the locking tooth that exists on the switching ring gear that is provided with that staggers mutually basically the switching time that this known timing switch can reach.Can only just can reach different switching times by changing switching ring gear with this timing switch thus.This means, though can reach switching time accurately during with this known timing switch, its original position because corresponding switch lever great-jump-forward or impact type ground fall back, thereby the elastic spring element of the switch contact that each sets is equally also handled on impact type ground, and can not adjust different switching times.

But in order to adjust this different switching times that are used for different task, known a kind of timing switch for example by DE 28 13 069 C2, wherein uses switch drum.The switch drum is provided with switch element, and they can switch to an off-position from a service position, passes through switch element console switch bar in the service position when the rotation of switch drum, and itself touches a microswitch again.Therefore the quantity of adjustable switching time only depends on the quantity that is arranged on the switch element on the switch drum circumference.Switch element quantity is big more, and the time interval between the adjustable single switch process is just more little.Switch lever is made the both arms scan shaft in this known timing switch, and it passes through a spring compression on the plug key of microswitch.Make scan shaft overcome spring force by switch element and be displaced to the position of the switch, make microswitch pass through its plug key and handle from original position.If a plurality of switch elements switch to its active position, scan shaft is being slided on the periphery at these switch elements during the rotation of switch drum on its service position so, till one or several switches to the switch element of non-active position until arrival.The end scan shaft impact type of effective switch element ground its original position that falls back again in the end, so microswitch also reopens to impact type in this switching process, switches to its original position in other words.Rouse the scan shaft that has the switch boss when continuing to rotate at switch and move towards the switch element that switches to active position again, and relatively slowly be offset to its position of the switch from its original position.Here shortcoming is, microswitch is just operated equally very slowly when switch lever moves so especially slowly, so its position of the switch or switching time are determined to inaccuracy very much.

In order to reach the intrinsic impact type switching process of switch, so-called during this period motion switch becomes as everyone knows (DE 3825308 A1), and it is worked according to super dead point principle.This switch is provided with the side plate switch, and it switches by switch lever, because the switch direction of switch lever is undertaken by the impact type of switch lever ground own, its original position if switch lever falls back is just this position of the switch can very accurately pre-determine so.But when switch lever climbs up one when switching to the switch element of active position, side plate switching surge formula ground can not accurately be determined from the moment that its inoperative position switches to its active position.Therefore the switching device that has this fast moving switch has adjusting device, must adjust switching time accurately with it.Secondly all electrical power is by the bearing transmission of side plate switch in this side plate switch of fast moving switch, and this causes burning out of bearing itself when switching current is big.This means that again the fast moving switch that has its side plate switch stands bigger wearing and tearing.Switch force is very little during this external this fast moving switch closure, therefore can not reach the closing of contact of fast moving switch the best reliably.

Summary of the invention

Therefore the objective of the invention is, improve the timing switch of this type in this wise, make under the situation of the elastic spring element of using the belt switch contact during, promptly both when power switch is connected, also when disconnecting, not only can reach and adjust switching time changeably but also can reach the accurately possibility of adjustment at two kinds of switching processes or switching time.

According to the present invention, a kind of timing switch is proposed, at least has one first and one second flexible spring element, they are provided with a switch contact separately at least, a rotation switch driven is bulging with having, it has a plurality of, selectively adjust to the switch lever of an effective or invalid position of the switch separately with respect to a rotatably mounted switch lever, deflect into the position of the switch by these switch element switch levers rotatably from the original position of an inoperative, and first spring element is contacted with the switch contact of its switch contact with second spring element, to realize switching process, wherein when continuing rotation, the switch drum falls back to the switch lever impact type its original position, so that throw off on switch contact impact type ground, it is characterized in that: establish a kayser bar, it moves to the second spring element direction by first spring element by the switch lever operation in closing course, the kayser bar is chimeric sealedly by the latch boss and the second spring element shape at a locked position of coupler during the first switch stage of closing course, two spring element distances that mutual maintenance is predesignated under the pretightning force effect that have switch contact; At second and then during switch stage in the first switch stage, the kayser bar shifts out from its locked position of coupler with the deflecting element that kayser bar function is connected in the second switch stage at least by one, and second spring element of second switch contact of impact type ground release, so that switch contact impact type ground is closed.

By guarantee the accurate switch of switch contact by timing switch structure of the present invention, to be switched on or switched off electrical appliance in the moment of predesignating.Establish a kayser bar, it moves to the second spring element direction by first spring element of being handled by switch lever in closing course for this reason.The kayser bar is connected with the second spring element shape by a latch boss sealedly during the first switch stage of the first spring element closing motion, makes the switch contact of second spring element have its switch contact and first spring element keep the distance of stipulating.That is to say that the kayser bar is in a locked position of coupler during the first switch stage of closing course, and chimeric sealedly by the latch boss and the second spring element shape.At this moment its switch contact of two spring elements keeps the distance of regulation mutually under the pretightning force effect.Being right after in the first switch stage back when the switch drum continues rotation has an equidirectional second switch stage, shifts out from its locked position of coupler by a deflecting element that is connected with kayser bar function during the second switch stage at least at this stage kayser bar.The rotary-percussion ground that kayser between latch boss by this skew kayser bar and second spring element of second switch contact or locking for example connect by the kayser bar lifts, so that switch contact impact type ground closure.

That is to say that this kayser bar is provided with in this wise, make it be in locked position of coupler at first switch in the stage, two spring elements that have its switch contact in this position keep the distance of regulation mutually under the pretightning force effect by the kayser bar.At this moment the first spring element kayser ground of the kayser bar and first switch contact is chimeric.Switch lever switches to the switch element of active position because switch lever especially little rotation deflection especially slowly in the unit interval by one of rotation switch driven drum in this first switch stage.First spring element by this deflection first switch contact moves to the second spring element direction of second switch contact lentamente by switch lever.But two switch contacts of first spring element and second spring element are owing to the kayser bar that is in locked position of coupler between spring element can not contact mutually.Be subjected to the effect of certain initial tension of spring at two spring elements in the end in the first switch stage.Follow directly in time that the kayser bar adjustment movement increasing along with spring element is offset when the second switch stage of the first switch stage back begins from its locked position of coupler.Discharge at second spring element of second switch stage end kayser bar, make switch contact impact type ground closed the second switch contact.Here the skew of kayser bar is undertaken by a deflecting element, can be adjusting tenon axle or a kind of slope of a fixed-site according to the different deflecting elements of kayser bar layout and supporting, climbs along this tenon axle or slope at the second switch stage of closing motion kayser bar.

Switch lever intrinsic in this timing switch has a probe in known manner, and it leans against on the periphery of switch drum.The switch element of this switch drum makes this switch boss along the skew radially outward of switch drum, makes switch lever make single-revolution motion, the switching process of facilitating the spring element that has its switch contact by this gyration.This skew is carried out very slowly usually, because the switch boss constitutes a kind of slope, with this slope it is slowly outwards slided during the rotation along the switch element that switches to active position at the switch drum, makes its skew.Because usually a plurality of switch elements of switch drum switch to active position, this effective position of the switch of switch lever remain to always until last switch element that switches to active position from the switch boss of switch lever is other move past till.In the end the tail rib of a switch element nuzzles up behind the switch boss, and the impact type leading thread is to inwardly dropping again immediately for this switch boss, so switch lever also falls back to its original position again.Because the falling of this impact type discharges to impact type first spring element of first switch contact simultaneously again, makes it return its original position again.The kayser bar is stuck on second spring element again during returning original position, therefore can restart the new switching process of Closing Switch contact.

Therefore by opening or closing by structure of the present invention, just the switching time of closure or cut-off switch contact can especially accurately pre-determine.Particularly can abandon being used for determining the auxiliary adjusting device of this switching time.Secondly owing to the quick-make and the disengagement of switch contact, the scaling loss of switch contact itself obviously reduces.In addition the intensity by spring element in other words the flexible parameter of this spring element select to determine definitely easily to make switch force contact force in other words between the switch contact to guarantee best contact closure all the time.

Can be used for power supply is accurately switched to another electrical appliance from an electrical appliance by timing switch of the present invention by structure of the present invention.Set the 3rd spring element that has the 3rd switch contact for first and second spring elements for this reason, it electrically contacts enduringly with its switch contact and the 4th switch contact that is arranged on second spring element, till being discharged by kayser bar impact type ground at second switch stage second spring element.In order to switch to first spring element from the 3rd spring element by the electric current of second spring element, the kayser bar is provided with a contact pin, makes the 3rd spring element be discharged the back at second spring element by impact type by it and remains on the distance of stipulating from the 4th switch contact of second spring element with its 3rd switch contact.Therefore the contact closure between the second switch contact of first switch contact of first spring element behind the handoff procedure of this impact type and second spring element, and the contact between the 4th switch contact of the 3rd switch contact of the 3rd spring element and second spring element is thrown off.

By the present invention, the kayser bar sets a deflecting bar, so that the kayser bar shifts out from its locked position of coupler, the switch deflecting bar second switch stage moves to a backstop.Guarantee to make things convenient for especially and make cheaply timing switch by this structure.

By the present invention, the layout of backstop and shape and the deflecting bar layout on the kayser bar is coordinated in this wise mutually, and the deflection that makes switch lever is along with the increasing hypergeometric of the switch motion (stroke) of spring element that has its switch contact or switch drum increases routinely.By this measure also can be accurate how determine switching time accurately.This means, till second switch stage end, continue to increase under the situation that rotatablely move (speed) that the offset movement speed of kayser bar is roused at switch remains unchanged.Therefore cause the very big skew of kayser bar in very little the rotatablely moving of switch stage end switch drum, so switching time can be adjusted extremely accurately.

By the present invention, the bolster of intrinsic switch lever can be used as the backstop of the offset arm of kayser bar.Reach the minimizing of timing switch the number of components thus, thereby make inexpensively.

By the present invention, be provided with a switch slide plate, it can enter one first position of the switch from original position.Be permanently affixed on its position of the switch at this first position of the switch switch lever.Therefore enter its position of the switch at the switch slide plate simultaneously from original position switch lever when move in its first position of the switch.Therefore the switch contact by two spring elements of timing switch of the present invention can enter lasting contact with the method for most convenient.This for example may need in the illuminating lamp of control constantly, the words of more permanent than the time of timing switch imagination itself if desired light.Secondly for example in order to test a kind of function of electrical appliance in short time, and the time that needn't change timing switch is adjusted, and also needs this switch.

By the present invention, the switch slide plate is movable to a second switch position, second spring element in this second switch contact, position is offset with respect to first spring element of first switch contact in this wise, even make switch contact still have the mutual spacing of a regulation when first spring element of first switch contact switches by switch lever.Make timing switch can have second kind of permanent state thus.That is to say that switch contact opens enduringly, therefore the electrical appliance that is connected above it can break away from running status constantly.For example prevent the switching process or the closure of switch contact if desired enduringly, this needs so, because use by repairing or change or for example not need in vacation by the terminal electrical appliance of timing switch connection of the present invention.

By the present invention, with so that the translation switch of the switch slide plate of second spring element skew moves through a leverage is delivered on second spring element.Can be convenient to especially change ground, the outside closely is installed in the timing switch housing easily by this leverage switch slide plate.

By providing a kind of timing switch, can extremely accurately adjust the disengagement and the closure of switch contact with this switch in a word by timing switch structure of the present invention.Two spring elements of first switch contact and second switch contact can be in two lasting position of the switch in addition, and it makes can have two kinds of lasting on off states, that is to say the lasting disengagement of switch contact and the lasting closure of switch contact.

Be connected with front end 65 functions of switch slide plate 43 at its position of the switch guide section 55 of adjusting to arrow 64 directions from original position, thus console switch bar 13.Switch lever 13 has one and is parallel to the switch pin 66 that rotating shaft 50 distributes on its hinge bar 44 for this reason, thereby also has whole switch lever 13 by front end 65 operations of this switch pin through switch slide plate 43 at hinge bar 44 when the direction of arrow 64 is adjusted.Cause the lasting closure of two

switch contacts

24 and 25 in this position of the switch, as the back also will describe in detail for Fig. 8.

If towards arrow 64 motions, it is connected with steering lever 45 functions opposite switch slide plate 43 so round about.Switch slide plate 43 has a switch boss 67 on the bottom surface of its guide section 55 in its front end 65 zones for this reason, and it is connected with adjusting lever 68 functions towards switch slide plate 43 of last steering lever 45 during against arrow 64 direction setbacks at switch slide plate 43.Here steering lever 45 can be rotated to support on the bigger supporting section 69 of a diameter of swinging axle 16, therefore is provided with a pin bearing platform 70 with a through hole 71.Be provided with second lever arm 72 on the pin bearing platform 70 of steering lever 45 on the side relative with adjusting lever 68, it has a mounting hole 73 that radially extends from pin bearing platform 70s.

As by Fig. 2 finding, housing rear wall 49 roughly has 74, the second steering levers 46 of another fulcrum post have a dead eye 75 with it pin bearing platform 76 and can be rotated to support on this fulcrum post below swinging axle 16 or supporting section 69.Steering lever 46 is provided with first adjusting lever 77 towards first steering lever 45 on its pin bearing platform 76, it has one and is parallel to the latch 79 that steering lever 46 rotating shafts 78 stretch, and the mounting hole 73 of the lever arm 72 of this latch and first steering lever 45 is chimeric.

Be provided with a joystick 80 on the pin bearing platform 76 of second steering lever 46 of a side relative with first adjusting lever 77, it is the part of steering lever 46 one, and axially staggering forward to rotating shaft 78.As seen from Figure 3, therefore roughly be positioned at the adjusting lever 68 same vertical planes of second lever arm 72 and first steering lever 45 at confined state joystick 80.Also reach the frame mode in special saving space by this structure.

It has an adjustment bearing pin 81 on the outer end of joystick 80, and it is used for adjusting second spring element 23 that has its second switch contact 25 when steering lever 46 revolutions.

Fig. 4 presses the complete switching mechanism of timing switch of the present invention under confined state with perspective representation.Shown in have its

switch element

11 and 12 in the position of the switch switch drum 3 be in such position of rotation, the radially inner switch element 12 that does not play on-off action is positioned at probe 20 zones of switch lever 13 in this position.Two

switch contacts

24 and 25 have a segment distance mutually in this is equivalent to the original position of the original position among Fig. 1, thus between these two members conduction connect.First spring element 22 leans against on the pin 34 or its manipulation section 19 of switch lever 13 in the outside.The bearing insert 37 interior kayser bars 35 that can be rotated to support on spring element 22 are fitted on the upper end rib 40 of second spring element 23 with its binding face 39.Secondly second spring element 23 leans against on the pin 34, and therefore second spring element 23 can be towards 22 motions of first spring element.Secondly between two

spring elements

22 and 23, can see the adjustment bearing pin 81 of steering lever 46 down.Shown in the inner surface 82 of these adjustment bearing pin 81 to second spring elements 23 of the position of the switch can have a very little distance, therefore second spring element 23 leans against on the pin 32 in the position of a regulation reliably.Secondly can see that the latch boss 38 of kayser bar 35 has equally with a certain distance from second spring element 23.Therefore shown in two spring elements 22 in the position of the switch and 23 relative position on the one hand by the original position of switch lever 13 or its pin 34, determine by the fixed position of pin 32 on the other hand.To the swinging axle 16 of switch lever 13 certain distance is arranged also at this location deflection bar 41, therefore two

spring elements

22 and 23 the original position of determining are not subjected to the influence of kayser bar 35.Secondly can see equally by Fig. 4 that the scan shaft section 18 of ending locking bar 35 and switch lever 13 that has its deflecting bar 41 roughly is positioned at same vertical plane.The manipulation section 19 of switch lever 13 is distributed in along the back of the axis direction scan shaft section 18 of the rotating shaft 50 of switch lever 13 and the back of kayser bar 35, and its reinforcement 52 blocks first spring element 22 in the back together with pin 34.Here two

spring elements

22 and 23 and the layout of kayser bar 35 and scan shaft section 18 select in this wise, their preceding boundary face or boundary edge are approached at least in a common vertical plane.

Original position is roughly with scan shaft section 18 with handle section 19 and meet at right angles the hinge bar 44 that is provided with its switch pin 66 both upper end rib 83 places of guide section 55 on vertical direction also is positioned at directly near switch slide plate 43 in the horizontal direction shown in this.Switch slide plate 43 is equally with two

kayser muscle

60 and 61 chimeric sealedly with kayser pin 58 shapes of guiding rib 56, feasible this neutral original position of floatless switch slide plate 43 definitely.This means, rotate to the direction of arrow 10 at switch drum 3, thereby do not influence automatic switch by switch slide plate during two spring elements 22 of acting in conjunction manipulation and 23 of switch lever 13 and kayser bar 35 in this neutral position of the switch of switch slide plate 43.Secondly because switch slide plate 43 also is in neutral position at two steering levers 45 of neutral position and 46, they do not influence automatic switching process equally in this position.

Can be clear that by Fig. 4, switching mechanism, regardless of the automatic part of forming by switch lever 13 and kayser bar 35, still all constitute a compactness and a narrow unit especially by switch slide plate 43 and two steering levers 45 and the 46 manual parts of forming, because timing switch 1 integral body has a narrow especially structure.

Fig. 5, two switch contacts 24 of expression and 25 each switch stages in 6 and 7 by

spring element

22 and 23 automatic switches.

The switch drum 3 that has its switch element of radially outward adjusting to active position 11 when the first switch stage began is in such angle position, directly leans against probe 20 in this position at those switch element 11 rear sides of direction of rotation front and forms on a kind of adjustment face 84 of slope.The switch lever 13 that has its scan shaft section 18 on this position that begins in the first switch stage and handle section 19 also is positioned on its original position, contacts with the switch element 12 that is in the invalid position of the switch in the outside in this position probe 20.As for Fig. 1 and 4 already mentioned, under slight pretightning force effect, leaning against switch lever 13 at this original position spring element 22 of switch lever 13 and handling on the pin 34 of section 19.Second spring element 23 is leaning against under the pretightning force effect on the pin 32 simultaneously, wherein guarantees between two

switch contacts

24 and 25 safe distance is arranged in this position.Kayser bar 35 is fitted on the upper end rib 40 of second spring element 23 with its binding face 39, and its latch boss 38 has the distance of a regulation from second spring element 23.Equally between the deflecting bar 41 of this original position kayser bar 35 and switch lever 13 supportings swinging axle 16 thereon, also be provided with a minimum distance at least.

Be it can also be seen that by Fig. 5 the scan shaft section 18 of switch lever 13 is opened a breach towards deflecting bar 41 in dead eye 48 zones, therefore kayser bar 35 directly is bearing on the swinging axle 16 with its deflecting bar 41 in switching process, and slides on it.Guarantee that thus switching process is not subjected to the influence of the mismachining tolerance of switch lever 13 and its scan shaft section 18, and can adjust accurate especially switching time.

Now the switch drum 3 that has its

switch element

11 and 12 from the angle position shown in Fig. 5 in follow-up operation rotates along arrow 10 directions, make switch lever 13 pass through its adjustment face 84 deflection radially outward with its probe 20, thereby switch lever is rotated to arrow 85 directions around swinging axle 16 along top effective switch element 11.Meanwhile along with the rotation sweep bar section 18 of switch lever 13 be positioned in addition the manipulation section 19 on its opposite and its pin 34 together equally to equidirectional around swinging axle 16 rotations.By this rotating spring element 22 along the direction of arrow to 23 deflections of second spring element.Because kayser bar 35 is bearing in the bearing insert 37 of first spring element 22, the kayser bar together with its latch boss 38 equally along the end motion on second spring element 23 of arrow 86 directions.The deflecting bar 41 of kayser bar 35 also to the motion of arrow 86 directions, contacts with the swinging axle 16 of switch lever 13 up to its preceding adjustment face 87 with its swinging axle one side.When switch drum 3 when the direction of arrow 10 is rotated further now because the continuation deflection of switch lever 13 continues to arrow 86 direction deflections first spring element 22, the kayser bar 35 of accompany movement rotates to arrow 88 directions by the deflecting bar 41 in the bearing insert 37 of spring element 22 that it leans against on the swinging axle, and the binding face 39 of kayser bar 35 is lifted from the upper end rib 40 of second spring element 23 lentamente.

Position of the switch when Fig. 6 represents that the first switch stage will finish, just in time also chimeric at this position kayser bar 35 with its latch boss 38 and second spring element 23.As seen from Figure 6, make first spring element 22 and second spring element 23 keep a predetermined distance by the distance between the bearing insert 37 of kayser bar 35 and the latch boss 38 and first spring element 22 with its upper end.The size of this distance is selected like this, makes to guarantee, two switch contacts 24 contact with 25 mutual can not conductions till the first switch stage finished.Therefore whole first switch in the stage two

switch contacts

24 and 25 have at least by the kayser bar 35 predetermined distances that in Fig. 6, can see.At this moment as has already been mentioned above like that by the slip of deflecting bar 41 along the swinging axle of switch lever 13, kayser bar 35 is to the rotation of arrow 88 directions, and the pin 34 of first spring element 22 by the manipulation section 19 of switch lever 13 continues to arrow 86 direction deflections.Simultaneously up to the first switch stage finish since sealed chimeric this spring element 23 of the shape of latch boss 38 on spring element 23 of kayser bar 35 also to arrow 86 direction accompany movements.

After first motion stage shown in Fig. 6, follow one second motion stage, the end of expression second motion stage among Fig. 7.As by Fig. 7 finding, switch drum 3 continues the direction of rotation motion to arrow 10, is fitted on the outer circumference surface 89 of switch element 11 with its probe 20 until switch lever 13 or its scan shaft section 18.Continue to the rotation of arrow 86 directions to its switch lever 13 the process of the position shown in Fig. 7 in position transition, make first spring element 22 continue to move by the pin 34 of handling section 19 thus to arrow 86 directions from the switch lever shown in Fig. 6 13.Because kayser bar 35 moves to arrow 86 directions equally by the bearing insert 37 of spring element 22, thereby make its deflecting bar 41 also to this direction motion, deflecting bar continues to lean against on the swinging axle 16 and upwards roughly slides to arrow 90 directions along it, and kayser bar 35 continues to rotate to arrow 88 directions.Therefore the latch boss 38 of kayser bar 35 is released in the spring element that has its switch contact 25 23 under the pretightning force effect immediately after in position shown in Fig. 6, therefore move to first switch contact 24 to its impact type, and contact with its conduction along arrow 91 directions towards closing direction.Switch drum 3 continues rotation along arrow 10 directions now, till probe 20 arrived radially in the zone of the switch element of inwardly adjusting 12 again, probe 20 fell back to it in the original position shown in Fig. 5 to impact type later at the last seamed edge 105 of wiping last radially outer switch element 11 of chance like this.Meanwhile first spring element 22 is got back to its pin 34 in the original position shown in Fig. 5 equally and is discharged, and makes kayser bar 35 fall back to equally again in the original position shown in Fig. 5.Simultaneously second spring element 23 also returns to the original position of its Fig. 5 again and leans against on the backing pin 32, thus therefore two switch contacts 24 and 25 since the whole switch lever 13 contrary arrow 85 direction impact types ground that fall and make of probe 20 impact types returning and impact type ground disengagement again.

Therefore because described by switch lever 13 with have leverage that the kayser bar 35 of its deflecting bar 41 forms and can determine

Closing Switch contact

24 and 25 and the switching time of throwing off two

switch contacts

24 and 25 definitely.

Secondly because this special construction also can be realized two kinds of lasting switches, the just position of the switch or the lasting position of the switch of throwing off of the lasting closure of two spring elements 22,23 that have its switch contact 24,25 are as in Fig. 8 and 9 for example the expression.Home position switch slide plate 43 from Fig. 5 moves to position shown in Fig. 8 by means of its action bars 62 along arrow 92 directions now.As seen from Figure 5, the switch bearing pin 66 of deflecting bar 44 is arranged under the following adjustment face 93 of switch slide plate 43 guide sections 55 in original position.Now enter position of the switch Fig. 8 shown in from it in the position shown in Fig. 5 together with its hinge bar 44 to arrow 92 direction moving switch bearing pins 66 by switch slide plate 43.At this moment whole switch lever 13 also rotates to arrow 85 directions around swinging axle 16 together with the hinge bar 44 and the joystick 19 of switch lever 13.The pin 34 that is arranged on joystick 19 ends continues to the motion of arrow 86 directions first spring element to be pressed equally to these arrow 86 directions with a horizontal component.Kayser bar 35 is done same rotatablely moving around bearing insert 37 to arrow 88 directions in this motion process, as Fig. 5,6 and 7 had been illustrated.This means, discharge the upper end of second spring element 23 at it reliably at the terminal position kayser bar 35 shown in Fig. 8, thus it since its elasticity pretightning force connect on first switch contact 24 that ground arrives first spring element 22 with its second switch contact 25 conductions.Therefore two switch contacts 24 and 25 closures.Can find out also that by Fig. 8 determined a swing position at this fixing terminal location of switch lever 13, it is equivalent to the final swing position of the switch lever 13 among Fig. 7 at least, but has changeed the several years to arrow 85 directions for the purpose of reliable more.

Till its action bars 62 of the slide plate of position switch shown in Fig. 8 43 usefulness moves to the backstop that penetrates opening 63 94 of running into roof 57 always.Be fixed on the kayser pin 58 of guiding rib 56 by kayser muscle 60 at this position switch slide plate 43.Switch lever 13 together with

spring element

22 and 23 and this of the affiliated switch contact 24 that is in contact with one another and 25 irrespectively reach the lasting connection of these two

switch contacts

24 and 25 in the position of the switch shown in Fig. 8 and the angle position of the switch drum of representing with imaginary line 3.Can enter a position of the switch that continues connection by this two switch contacts 24 of structure and 25 by timing switch of the present invention.

, be provided with two steering levers 45 and 46 now, as seen from Figure 9 in order to ensure the position of the lasting disconnection of two switch contacts 24 and 25.From the original position of Fig. 5 switch slide plate 43 is moved to arrow 95 directions again now, make it with its kayser muscle 61 kaysers at kayser pin 58 places and lean against on second backstop 96 that roof 57 penetrates opening 63.Be fixed on kayser pin 58 places at this position switch slide plate 43 by kayser muscle 61, as seen from Figure 9.As Fig. 2 and 3 had been narrated, on the following adjustment face 93 of switch slide plate 43 guide sections 55, be provided with switch boss 67.In adjusting lever 68 actings in conjunction, and make them around the direction of rotation rotation of the supporting section 69 of swinging axle 16 to arrow 97 with switch slide plate 43 this switch boss 67 and steering lever 45 when arrow 95 directions are adjusted.By this of steering lever 45 adjust that motion makes second steering lever 46 simultaneously since its mechanical connection by peg graft pin 79 and mounting hole 73 around its supporting shaft 74 to opposite spin.Being undertaken one by the adjusting pin 81 of this gyration on joystick 80 lower ends of steering lever 46 along the direction of rotation of arrow 98 has along the adjustment campaign of the horizontal component of arrow 99 directions.Do not influence first spring element 22 yet adjust motion by this, therefore the distance between these two switch contacts 24 in second kind of position of the switch and 25 of switch slide plate 43 and steering lever 45 and 46 obviously enlarges.Because the gearratio between switch slide plate 43 and two steering levers 45 and 46 is selected in this wise to the adjustment campaign of arrow 99 directions, even the switch contact 24 of winning also can not contacted with switch contact 25 reliably in effective position of the switch of first spring element 22 (as shown in Figure 7).

Because the present invention uses by switching mechanism of the present invention by the structure of Fig. 8 and 9 and can adjust two extreme positions position of the switch in other words enduringly.That is to say the lasting connection of carrying out to reach

switch contact

24 and 25 closures on the one hand by Fig. 8.For Fig. 9 too, that is to say in the contact, second position of the

switch

24 and 25 of switch slide plate 43 and disengage lastingly reliably.

Figure 10 represents to have the embodiment of a kayser bar 35/1, and this kayser bar is the part of the one of first spring element 22/1.Wherein be provided with one first switch contact 24/1 on first spring element 22/1 in the upper area, it is positioned at from the distance that is arranged on second switch contact 25/1 regulation on second spring element 23/1 in the original position shown in spring element 22/1 and the spring element 23/1.Kayser bar 35/1 is being created on first spring element 22/1 integratedly by a spring section 100 of roughly making annular above first switch contact 24/1.Shown in original position kayser bar 35/1 be substantially perpendicular to first spring element 22/1 and stretch, and it is downward to have an approximate vertical, to the latch boss 38/1 of second spring element, 23/1 bending.Be provided with the stop element 101 of an electric insulation in the upper end of second spring element 23/1, it for example is made up of plastics, for example can be injection-moulded on the upper end of second spring element 23/1.Here latch boss 38/1 is selected less than the distance of two switch contacts 24/1 and 25/1 to the horizontal range of this stop element 101, if therefore when first spring element 22/1 during to arrow 102 direction deflections latch boss 38/1 and stop element 101 chimeric, just two switch contacts 24/1 and 25/1 remain on mutual nonconducting distance reliably.Other functions are equivalent to the embodiment to the kayser bar 35 of the above-mentioned explanation of Fig. 5 to 9, and wherein the manipulation of first spring element 22/1 is carried out at its pin of handling on section 19 ends by switch lever 13 or its equally.It has a deflecting bar 41/1 equally in order to make 35/1 deflection of kayser bar, and it is created on the kayser bar 35/1 integratedly.In the embodiment of Figure 10 kayser bar 35/1 after the regulation distance of passing by along arrow 102 directions upwards to arrow 103 direction deflections, therefore period second in second switch stage spring element 23/1 discharged by impact type ground equally.In order to ensure, the kayser bar 35/1 that has its latch boss 38/1 when the direction recoil movement of contrary arrow 102 kayser at stop element 101 places, stop element 101 has a deflection plane 104 that tilts on its back side, make kayser bar 35/1 can return to the original position shown in Figure 10 reliably.For the original position of fixing second spring element 23/1 is provided with a pin 32 equally, be arranged in the housing of unillustrated timing switch among Figure 10 to its fixed-site.

Figure 11 represents the another kind of embodiment of the supporting of kayser bar 35/2 on first spring element 22/2.Here kayser bar 35/2 for example can be made of metal material or plastics, wherein is provided with the stop element (not drawing among the figure) of an electric insulation under first kind of situation on second spring element equally according to the embodiment of Figure 10.For kayser bar 35/2 can rotatingly support on first spring element 22/2, this first spring element 22/2 has two bearing

grooves

108 and 109 in its

lateral edges

106 and 107 the zone in the zone in the top, inserts wherein by their two

support plates

110 and 111 that are arranged on the kayser bar 35/2 with corresponding spacing.Two

support plates

110 and 111 bending that makes progress at the rear side place in described embodiment makes kayser bar 35/2 be fitted in the support edges 112 of extending between two

support plates

110 and 111 on the front side of spring element 22/2, and can upward deflect around this support edges 112 with it.Other structures of kayser bar 35/2 can be the same with the structure of kayser bar 35/1 among Figure 10.

Secondly also it is contemplated that other structures of the supporting of kayser bar on first spring element.Here important only is, this kayser bar, and as for example represented by arrow 103 vertically upward in Figure 10, can be to this direction deflection.Here the readjustment at that time kayser bar can be provided with the spring element that does not draw in detail in the drawings, it both can be installed in the kayser bar, on the spring element, also can be installed in the housing of timing switch, and kayser bar is at that time loaded with contrary arrow 103 directions of corresponding spring force.Being connected also of kayser bar itself or it and first spring element can be represented as the embodiment by Figure 10 particularly, makes resilient.Secondly also imagine, in the kayser bar is bearing in respective track in the housing movably along arrow 102 directions of Figure 10, and the corresponding construction by gathering sill in the housing by one-sided or bilateral the guide finger that is arranged in this gathering sill of embedding on the kayser bar cause deflection by the mode of crescent guiding.Certainly, shown in the embodiment of Figure 10, under any circumstance do not allow to exist between first spring element and second spring element conduction to connect by the kayser bar.This on the one hand can be by kayser bar itself the corresponding selection of material reach, reach by the insulation measures of adding on kayser bar or the spring element on the other hand.

An embodiment of Figure 12 and 13 expression switch contact structures, it makes so-called transfer contact.

Be provided with one first spring element 22/3 and one second spring element 23/3 in this construction of switch, they are equivalent to the spring element 22 and 23 among the embodiment of Fig. 5 to 9.Therefore each upper end in each spring element 22/3 and 23/3 is provided with one first switch contact 24/3 and another switch contact 25/3, and they have the distance of regulation each other in the original position shown in Figure 12.For distance first spring element 22/3 that forms this regulation is leaning against under the pretightning force effect on the pin 34/3 corresponding to the original position that the embodiment of Fig. 5 represents there, pin itself is arranged on the outer end of manipulation section 19/3 of switch lever 13/3.Switch lever 13/3 can support pivotally around swinging axle 16 equally.Secondly second spring element 23/3 is fixed on it on the original position shown in Figure 12 by pin 32, therefore guarantees that two switch contacts 24/3 have regulation, the non-conductive distance that is connected each other with 25/3.Also being provided with the 3rd spring element 113, the three switch contacts with one the 3rd switch contact 114 except that these two spring elements 22/3 and 23/3 conducts electricity enduringly with the 4th switch contact 115 of second spring element 23/3 and contacts.This 4th switch contact 115 be arranged on second spring element 23/3 and second switch contact 25/3 back-to-back.The imagination of being not difficult is provided with another conductive plate according to the type of two conductive plates 26 among Fig. 1 and 29 for spring element 113, and itself is connected (not drawing in the drawings) with one the 3rd binding post again.The 3rd spring element is subjected to the pretightning force effect, so its switch contact 114 leans against the 4th switch contact 115 equally under the pretightning force effect, and therefore it can not unexpectedly lift from the 4th beginning contact 115 in the original position shown in Figure 12.In order to switch by having its four switch contacts 24/3, three spring elements 22/3 of 25/3 and 114 and 115,23/3 and 113 " transfer contacts " that constitute are provided with a kayser bar 35/3, it has a latch boss 38/3, and it is equivalent to the latch boss 38 of the switch lever 35 among Fig. 5 to 7 in its original position and function aspects.Connect a upwards binding face 39/3 of compression frontward equally in these latch boss 38/3 upper edge arrow 102 directions.

Secondly be provided with vertically downward a switch from latch boss 38/3 a distance and refer to 116, its length that stretches is vertically downward done obviously greater than latch boss 38/3 in described embodiment.Roughly this switch refer to 116 above a deflecting bar 41/3 is arranged equally, its working method is equivalent to the deflecting bar 41 of the embodiment among Fig. 5 to 7 equally.

So switch lever 13/3 same execution along the oscillating motion of revolution arrow 85 directions, if the switch drum of representing with imaginary line 3 that has its switch element 11 and 12 rotates to arrow 10 directions from original position shown in Figure 12.At this moment make spring element 22/3 roughly to the skew of horizontal arrow 102 directions by pin 34/3, directly end the latch boss 38/3 and second spring element 23/3 chimeric till.Refer to that at this position switch 116 also have with a certain distance from the 3rd spring element 113 in the horizontal direction, therefore two switch contacts 114 continue to keep lasting contacting with 115.Secondly latch boss 38/3 is arranged on the kayser bar 35/3 equally in this wise, makes during the first switch stage two switch contacts 24/3 and 25/3 keep the distance of regulation mutually.The kayser bar 35/3 that has its deflecting bar 41/3 at the end in this first switch stage contacts with the swinging axle 16 of switch lever 13/3, and begins to revolution arrow 88 directions around its bolster revolution in the beginning that is right after in second switch stage of its back.Even switch refers to continue between the 116 and the 3rd spring element 113 to keep a safe distance in this state, therefore two switch contacts 114 continue to keep mutual conduction to contact with 115.

Turn round the direction of arrow 85 when revolution is continued in the final position shown in Figure 13 on switch lever 13/3 edge, latch boss 38/3 is deviate from second spring element, the 23/3 impact type ground that has two switch contacts 25/3 and 115 now, because kayser bar 35/3 also continues along the rotation of revolution arrow 88 directions when this adjustment campaign of switch lever 13/3, thereby has both made latch boss 38/3 also make switch refer to that 116 roughly move both vertically along vertical arrows 103 directions.As seen from Figure 13, throw off latch boss 38/3 back the 3rd spring element 113 at second spring element 23/3 and lean against switch and refer on 116 the lower end, and remained on the fixed position shown in Figure 13 by it.Because unclamped to spring element 23/3 impact type by latch boss 38/3, therefore the contact between two

switch contacts

114 and 115 is also thrown off on impact type ground, and then impact type ground is closed for a moment two switch contacts 25/3 and 24/3 after very short time after this.

Therefore use by the construction of switch of the embodiment in Figure 12 and 13 can from first electrical appliance impact type switch to second electrical appliance, wherein for example first electrical appliance and has the corresponding binding post conduction that is equipped on first spring element that has its switch contact 24/3 and contacts, and second electrical appliance is equipped on the 3rd spring element 113 that has its switch contact 114.As for Fig. 5 to 7 illustration, by making the switch lever 13/3 contrary direction of arrow 85 impact types ground fall back to the method for the original position of its Figure 12 again, in case it arrives in the active zone of inoperative switch element 12, spring element 22/3,23/3 and 113 just from its final position impact type shown in Figure 13 return to it in the original position shown in Figure 12.

Therefore generally speaking can conclude, use accurate, the automatic switch that to adjust

switch contact
