Claims

[Scope of utility model registration request]

A main circuit operating part and a sub-circuit operating part are provided on an operating piece that is always energized to return, and when the operating piece is pressed, the main circuit is made conductive through the main circuit operating part, and this state is maintained. The switch is equipped with a metal fitting and a locking mechanism, and the main circuit is opened by pressing the operating piece, and the sub-circuit operating piece opens the sub-circuit just before the main circuit changes from the conductive state to the open state by pressing the operating piece a second time. A switch with a muting circuit connected to the sub-circuit to cut off pulse noise caused by arcing that occurs when the main circuit is opened. ,
