スイツチ。 A case with multiple contact electrodes arranged on each side,
A movable body is provided in the case so as to be movable up and down, and is pushed down by a push operation of an operation knob that protrudes above the case, and is returned downward by a return spring provided in the case; In a push switch equipped with a contactor that selectively shorts the plurality of contact electrodes by vertical movement of a movable body, a cam plate having an endless cam groove formed in a surface facing the movable body in the case can be moved laterally. The movable body is provided with a lock pin movable in the axial direction that engages with the cam groove of the cam plate at the tip and locks the movable body in a depressed state. A push switch characterized by being provided with a spring member that presses into contact with the bottom surface of a cam groove of a plate.
