Preferably, an insulating cover layer is adhered to the top of the pressing block by an adhesive.

Preferably, stop gear includes that the symmetry is installed at two stopper according to the briquetting left and right sides, two relative inside walls in the rectangle mouth are seted up symmetrically and are supplied two stopper to slide to insert two spacing grooves of establishing.

Preferably, the rebounding mechanism comprises a U-shaped frame fixed at the bottom of the top cover, the tail end of the U-shaped frame is movably connected with a partial supporting rod through a pin shaft, a supporting head is arranged on the upper end cover of the partial supporting rod, the outer edge of the supporting head is abutted against the bottom of the pressing block, and one side of the lower end of the partial supporting rod is connected with the bottom of the top cover through a spring.

Preferably, the pushing head is made of rubber materials.

Preferably, the spring is a strong compression spring.

The utility model has the advantages that: can ensure through the effect of resilience mechanism and press the piece and can both reply the normal position after pressing at every turn for press the piece to break away from and reply not smooth drawback before pressing according to on the metal film switch, improve the service cycle of pressing the piece greatly, ensure electrical equipment's normal use.
