Abstract
The utility model relates to an electric element, in particular to a switch device. The switch device is composed of a shifting block and a seat body. Wherein, the shifting block is hinged on the seat body. A top post and a compressing spring are arranged inside the shifting block. A copper wire connecting post, and a first contact point and a second contact point or an insulation point which are positioned on two sides of the copper wire connecting post are arranged inside the seat body. A movable contact sheet which can swing towards the two sides is installed on the copper wire connecting post. The upper surface of the movable contact sheet and the lower end surface of the top post form slide matching connection. A forced debuckled point is arranged on the corresponding matching position of the movable contact sheet and the lap shell body of the shifting block for installing the top post. The utility model forcedly separates and breaks the movable contact sheet which is accidentally welded and adhered by the electric arc generated by electric current from a static contact point by that the edge of the lower end of the lap shell body of the shifting block is arranged on the forced debuckled point on the movable contact sheet and rigidity shift is used.

As shown in Figure 1, existing switching device includes pedestal and shifting block, wherein shifting block is hinged on the pedestal, in the pedestal of insulation, two or three copper binding posts are set, middle one as public binding post, be placed in as the movable contact spring of active lever and be symmetricly set on the supporting seat that has groove in the pedestal, directly or indirectly be connected with the conducting of middle copper binding post, compression spring and fore-set are installed in the containing cavity of the bottom housing of button successively, the lower end of fore-set and movable contact spring upper surface constitute flexible connection, on this movable contact spring, can horizontally slip, make movable contact spring one end depress, an end lifts, and movable contact spring can only be contacted with a contact in insulating point or another fixed contact with the fixed contact on both sides.Open/break in the process at this, the silver point and the fixed contact that are arranged on the movable contact spring are welded adhesion by the electric arc accident that electric current produced easily, pressure owing to the shifting block spring when disconnecting is too small, can't be with movable contact spring and fixed contact disjunction, switch loses on-off function, cause switch unreliable, influence the useful life of switch.
Summary of the invention
The utility model provides a kind of simple in structure in order to solve the weak point that above-mentioned prior art exists, and can force to thread off long service life, safe and reliable switching device.
For achieving the above object, the utility model adopts following scheme: a kind of switching device, form by shifting block and pedestal, wherein shifting block is hinged on the pedestal, be provided with fore-set and compression spring in the shifting block, be provided with the copper binding post in the pedestal, and be in first contact and second contact or the insulating point of its both sides, be mounted with the moving movable contact spring of to swing sideward on the copper binding post, the upper surface of movable contact spring and the lower surface of fore-set constitute sliding connection, and described movable contact spring is provided with the pressure trip point with the shifting block bottom housing corresponding matching place that fore-set is installed.
The utility model further is set to: the lower edge of described shifting block bottom housing is stirred with the pressure trip point formation that is arranged on the movable contact spring upper surface and is cooperated.
Described movable contact spring upper surface is symmetrically arranged with the pressure trip point.
The beneficial effects of the utility model are: by improving on existing shift knob device, original movable contact spring upper surface with the shifting block bottom housing corresponding matching place that fore-set is installed the pressure trip point of two symmetries is set, open/break in the process at the shifting block switch, silver point on movable contact spring and fixed contact are welded adhesion by the electric arc accident that electric current produced, when the pressure by fore-set can't be with movable contact spring and fixed contact disjunction, the utility model is stirred the pressure trip point that is arranged on the movable contact spring by the edge of shifting block bottom housing lower end, utilize rigid stirring, pressure is with movable contact spring and fixed contact disjunction, it is simple in structure, rationally, easy to use, the reliability and the useful life that have strengthened switch.
Below in conjunction with drawings and Examples the utility model is further specified.
