Claims

[Scope of utility model registration request]

It comprises a terminal plate on which three fixed contacts are arranged, a movable body that is moved forward by a bushing operation and returned by a return spring, and a short circuit that is supported by the movable body and comes into elastic contact with the surface of the terminal plate, and The three fixed contacts are arranged side by side in a direction intersecting the moving direction of the movable body, with the center contact being a common contact and the contacts on both sides being selective contacts, and the short circuit is connected to the movable body. The terminal plate is pivotably supported so as to be able to swing in the direction in which the contacts are arranged, and a pin protruding from the short circuit is guided on the terminal board so that the short circuit swings as the movable body moves. A two-stage switching bushing switch that has a cam groove for moving the switch, and the cam groove is an endless groove with separate outward and return paths.
