Protruding stupefied extrusion removal end, the protruding upward movement of joint is followed to the slider, and the slider compression elastic component. When the conductive projection of the cantilever is abutted against the switch function piece, the switch is in a conducting state at the moment.

The user stops pressing the bottom of the keypad and removes his hand from the keypad. The key panel rotates with the hinge protrusion as an axis. The piece that resets extends, and restores to the original state, and the piece that resets promotes key panel reconversion. At the same time, the elastic member is stretched and restored to its original shape. The elastic piece pushes the sliding piece to move downwards along the clamping bulge. The auxiliary member moves in a direction approaching the key holder, and the protruding edge of the auxiliary member changes from the interference state shown in fig. 2 to the interference state shown in fig. 1. The limiting protrusion slides out of the U-shaped groove. The wall switch returns to the original state and the switch is still in a conducting state. When the user presses the key panel again, the switch is powered off.

The arrangement in this application may be seen as one part being integrally formed with another part, or one part being adhesively bonded to another part, or one part being secured to another part by screws or bolts.
