Abstract
A cam of a safety switch rotates about a rotational shaft in accordance with an operation of inserting an actuator into an opening and an operation of withdrawing the actuator. A switch part includes an operation rod that reciprocates according to a rotation angle of the cam, and detects an insertion state where the actuator is inserted in the opening. In the insertion state, a locking member locks the actuator upon engagement with a part of the cam. When the operation of withdrawing the actuator is performed in a locked state of the actuator, the cam pushes the locking member in one direction, and the locking member pushes a part of a head case in the one direction. This improves locking strength of the safety switch.
