Abstract: To realize both toughness and size reduction of a safety switch. A safety switch is a safety switch into and from which a bolt of an actuator is inserted and pulled out. The safety switch includes a casing having a shape elongated along a first direction, a metal head having a receiving space for receiving the bolt of the actuator and provided on a first end side of the casing in the first direction, a detector for detecting a first state in which the bolt is received in the receiving space, a lock mechanism, a switching device and a first attachment portion provided in the head and having a first attachment hole into which a first attachment member is inserted.
