A safety switch is provided in which the open-close condition of a switching contact provided in a lock mechanism is reliably switched in a manner coupled with a motion of a lock member between a lock position and a unlock position. Since a link member, which directly and simultaneously switches the open-close conditions of normally-open and normally-closed switching contacts pursuant to the motion of a lock member, is provided, the open-close conditions of the normally-open and normally-close switching contacts can be switched reliably in a coupled manner with the motion of the lock member between the lock position and the unlock position. As a result, for example, by monitoring the open-close conditions of the normally-open and normally-close switching contacts, it is possible to determine to which of the lock position and the unlock position the lock member has moved, that is, which of the locked state and the unlocked state the rotation of the drive cam is in.
