Technical field
The utility model relates to a kind of sensitive switch.
Background technology
Sensitive switch has small contact separation and snap-action mechanism, carries out the contact mechanism of switch motion by the stroke of regulation and the power of regulation.
Traditional sensitive switch, it, by the sincere side at glue shell, is not suitable for the operation of larger operating mechanism, and, two or three terminals of sensitive switch all towards same direction, terminal and terminal pitch less, be not suitable for using under the adverse circumstances such as moist, sand and dust or open air.This kind of traditional sensitive switch, its internal structure is comparatively complicated, and parts are many, and then reduces the reaction sensitivity of switch entirety, also improves the manufacturing cost of switch simultaneously.
Utility model content
The purpose of this utility model overcomes weak point of the prior art, provide a kind of structure simple, be quick on the draw, the sensitive switch of low cost of manufacture.
The purpose of this utility model is achieved through the following technical solutions:
A kind of sensitive switch, comprising: housing, by sincere, Chang Kaiduan is sub, public terminal, moving plate and spring;
Described Chang Kaiduan and described public terminal are arranged in described housing, and described Chang Kaiduan and described public terminal lay respectively at the two ends of described housing;
Described Chang Kaiduan is provided with fixed contact, and described moving plate is contained in described housing, and described moving plate is provided with moving contact, and described fixed contact mutually abuts with described moving contact or is separated;
Described spring one end is connected with described public terminal, and the described spring other end is connected with described moving plate;
Describedly be arranged in described housing by sincere slip and abut with described spring.
Preferably, described housing comprises: face-piece and drain pan, described face-piece and described drain pan offer semi-circular through hole respectively, described face-piece is connected with described drain pan, the semi-circular through hole laid respectively on described face-piece and described drain pan is connected to form manhole, is describedly arranged in manhole by sincere slip.
Preferably, be describedly provided with bootstrap block by sincere, described inner walls offers guiding groove, and described bootstrap block slides and is located in described guiding groove.
Preferably, described spring is hook spring.
Preferably, described face-piece is formed in one structure.
Preferably, described drain pan is formed in one structure.
Be provided with bootstrap block by sincere, inner walls offers guiding groove, and bootstrap block slides and is located in guiding groove.By coordinating of bootstrap block and guiding groove, can make to slide on more stably on housing by sincere, improve the stability of sensitive switch, and then improve the sensitivity of sensitive switch.
By pressing by sincere, slide along housing by sincere, make to abut with spring by sincere one end, spring is subject to by sincere pressing force, and then drive connected moving plate to make rocking action, thus the moving contact realizing moving plate contacts with each other with the fixed contact of Chang Kaiduan or is separated, and realizes being switched on or switched off of power supply.
Sensitive switch by arrange housing, by sincere, Chang Kaiduan is sub, public terminal, moving plate and spring, structure is simple, is quick on the draw, and low cost of manufacture.
