Description

A reset metal button switch

technical field

The utility model relates to the technical field of switch structures, in particular to a reset metal button switch.

Background technique

A push button switch refers to a switch that uses a button to push the transmission mechanism to control the connection or disconnection of the moving contact and the static contact and realize circuit switching. Button switches are widely used in electrical automatic control circuits. Button switches generally include a push switch assembly. The side wall of the foot seat is provided with a tension spring slider and a compression spring slider that can slide up and down. The extension spring slider is connected with the moving contact piece and can control the connection or disconnection of the moving contact piece and the static contact piece. On the other side of the tension spring plunger. The decorative performance of the existing key switch is not strong, thereby limiting its application range.
