The utility model further is set to: the position of described movable contact spring one end is corresponding with controll block as press-side, the other end and position with often open static contact and normally closed static contact is corresponding as link, the width of described movable contact spring from link to installation end increases gradually.
By adopting technique scheme, movable contact spring when being through at brace by the elastic thrust of flexure strip, make installing port slowly from the movable contact spring thinner end to the thicker end slippage until locking.
The utility model further is set to: the opposite side of the relative controll block of described movable contact spring press-side is provided with the back-moving spring of fitting with movable contact spring, is provided with the installation cavity suitable with back-moving spring in the described housing.
By adopting technique scheme, when can't resetting movable contact spring, gives by back-moving spring an one power-assisted, and secondly back-moving spring and controll block are also assisted the location of movable contact spring as two point of applications.
The utility model further is set to: be provided with the spill mounting groove towards brace in the described housing, described spill mounting groove cooperates the movable contact spring installation cavity that constitutes sealing with installing port.
By adopting technique scheme, earlier movable contact spring is through at installing port, again movable contact spring and brace are installed on the spill mounting groove, make movable contact spring lock in the chamber to deviate from.
The utility model further is set to: described spill mounting groove corresponding shell edge is provided with the opening that passes for brace, and described opening is provided with the waveform lines towards the inboard of brace.
By adopting technique scheme, the waveform lines increases opening frictional force, slippage when avoiding brace to install.
The utility model further is set to: the relative housing of described opening protrudes and arranges, and described brace is provided with the bayonet socket suitable with the opening projection.
By adopting technique scheme, bayonet socket and opening projection cooperate vertically locatees brace.
The utility model further is set to: described housing comprises base and loam cake, lays respectively at brace one side on the described base and is provided with briquetting, and the briquetting cooperation of described base and loam cake is locked in housing with brace.
By adopting technique scheme, the briquetting of base and loam cake carries out located lateral to brace.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
