Claims

[Scope of utility model registration request]

A lever-shaped actuator made of an elastic plate material with a branched base end and a pair of engaging pawls protruding outward on both sides of the tip of the branch, and a left and right mounting groove for the base end of the actuator formed on the top surface of the case. It consists of a switch body with a pair of shaft holes drilled in the side wall, and a pair of engaging pawls of the actuator are swingably supported by the pair of shaft holes of the switch body, and when the actuator swings downward, the upper surface of the case A mounting opening for inserting at least one engaging pawl of an actuator into a shaft hole from a side surface of a case in a micro switch that operates a movable contact spring having a snap action mechanism by pressing down a push button protruding from the case. is formed on the side of the case.
