The lever (40) and both holders (20) and (30) are coaxially and rotatably coupled with a supporting shaft (11) of a case (10). Projections (43) and (44) formed on the upper and lower sides of the front end of the lever (40) are accommodated in cam holes (22) and (32) of the holders (20) and (30). When the lever (40) is rotated, the movable contact (24) of the first holder (20) is brought into contact with or separated from a first terminal (12) and the holder (20) switches a winker circuit. The movable contact (36), etc., of the second holder (30) are brought into contact with or separated from a second terminal (62) and the holder (30) switches other circuits such as a position circuit. When the lever (40) is pushed in, they are push-canceled and return to neutral positions. Thus, the two circuits can be switched with one lever and uneven wear of the contacts can be prevented.

Description

Push-cancel switch for winker

The present invention relates to (automobile-used) signal lamp pushing releasing formula switch.

Push-cancel switch for winker has been known technology, for example, disclosed switch in real fair 4-6111 number, it has with lower member; Shell; The terminal that connects with tally circuit, but the supporting plate of free rotaring ground supporting in housing which is provided with and above-mentioned termination contact or the travelling contact that separates; Make this pallet rotary handle, with supporting plate remain on the rotary position of setting or centre position maintaining body, with handle lead the guide in centre position, make supporting plate return the resetting cam mechanism in centre position, the terminal base that is covered the shell aperture during from middle position pushing handle from rotary position.

Yet, under the situation of said structure, only establish a circuit, and supporting plate only is located at the one-sided of handle, so cause the mill of contact portion inclined to one side easily.

The purpose of this invention is to provide a kind of difficult mill partially and the pushing with many circuit remove the formula switch.

For solving above-mentioned problem, the related push-cancel switch for winker of the present invention is a prerequisite with above-mentioned open example, and has following feature; Further terminal is made and be located on the housing and joining the 1st terminal of any circuit tally circuit or other circuit and be located at the 2nd terminal that connects with the 1st terminal and other circuit on the terminal base, simultaneously, supporting plate is provided in the both sides of handle and guide line, the 1st supporting plate is equipped on the 1st terminals side, the 2nd supporting plate is equipped on the 2nd terminals side, and each supporting plate is driven and turned round by handle or other supporting plates.

The 1st supporting plate and the 2nd supporting plate can be coupled together by link, and link can be made of the fitting projection that is located at the chimeric recess on the supporting plate and be located on another supporting plate.

Have again, cam mechanism and maintaining body can be located on the 1st supporting plate and the 2nd supporting plate simultaneously.Also cam mechanism can be located at either party of the 1st supporting plate or the 2nd supporting plate, and maintaining body is located at the opposing party, cam mechanism and maintaining body only can also be located on either party of the 1st supporting plate or the 2nd supporting plate.

On the other hand, also the 1st supporting plate and the 2nd supporting plate can be in disengaged state.In this case, cam mechanism and maintaining body can be located at respectively on the 1st supporting plate and the 2nd supporting plate, also cam mechanism and maintaining body only can be located in the 1st supporting plate or the 2nd supporting plate, another supporting plate can turn round together with handle.

In addition, also cam mechanism and maintaining body can be located on any in the 1st supporting plate or the 2nd supporting plate, and on another supporting plate, only establish maintaining body, in such cases, cam mechanism has is located at the jut that cooperates with cam hole that is roughly pentagonal cam hole on the anchor clamps and is located at the projection of direction up and down on the handle, and the supporting plate that only has a maintaining body cam hole can be made be roughly dimetric.

According to the present invention, the supporting plate that is disposed at handle and guide line both sides turns round at opposition side, so the mill of contact portion is partially very little, can keep good operating characteristics over a long time, and can prolong the useful life of switch.

In addition, if the 1st supporting plate and the 2nd supporting plate are linked up, the travelling contact of each supporting plate engages, throws off with the 1st terminal and the 2nd terminal, carries out the switching of tally circuit and other circuit by a handle, and so just the switch that the past can be provided with respectively focuses in the single switch case.And then, because an available handle is operated two circuit, thus the handle number is reduced, simple to operate, can reduce number of components and obtain good operability.And can provide the switchette that to operate two circuit.

In this case, implement being connected of two supporting plates with fitting projection, will make to connect reliably, and be easy to assembling by the chimeric recess that is located on the supporting plate.

In addition, if cam mechanism and maintaining body are located on the 1st and the 2nd supporting plate, operability can improve and reliably more.With respect to this,, holding member is located at the purpose that then can reach the reduction parts on another if cam mechanism is located on any one of the 1st supporting plate the 2nd supporting plate.It also is same only being located at cam mechanism and maintaining body on either party of the 1st supporting plate or the 2nd supporting plate.

On the other hand, if the 1st supporting plate and the 2nd supporting plate are not engaged, then supporting plate can be distinguished independent revolution.In this case, if cam mechanism and maintaining body all are located at the 1st supporting plate and the 2nd supporting plate respectively, then the travelling contact of each supporting plate and the 1st terminal, reach the connecing from being synchronous of the 2nd terminal.And if cam mechanism and maintaining body only are located in the 1st supporting plate or the 2nd supporting plate any one, another supporting plate and the rotating words of handle one, then travelling contact is to carry out simultaneously with the revolution of handle with separating being connected of terminal on the one hand.And the joint of the travelling contact of each supporting plate and the 1st terminal and the 2nd terminal or to separate be nonsynchronous.

And then, if cam mechanism and maintaining body are located in the 1st supporting plate and the 2nd supporting plate any one, and on another supporting plate, only establish maintaining body, under the situation that a supporting plate pushing is removed, another supporting plate can keep its previous status.In this case, cam mechanism is by being located at being roughly pentagonal cam hole and being located on the handle up and down the direction projection and constituting with cam hole engagement protrusion portion on the supporting plate, only there is the supporting plate cam hole of maintaining body to make roughly 4 angular shapes, so, the 1st supporting plate only is that with the part difference of nonsynchronous push-cancel switch for winker the shape of cam hole is different with the synchronous push-cancel switch for winker of the 2nd supporting plate action, and this just can reduce the mould of part.
