Abstract
To prevent incoincidence of contacts, a safety switch switches the contacts by cooperation of an actuator and a switch body. The switch body includes an operating cam and a locking cam that rotate due to insertion of the actuator, an operating rod that switches the contact according to rotation of the operating cam, and a locking lever that is movable toward and away from the locking cam such that the locking lever takes a lock position in which it locks rotation of the locking cam and an unlock position in which it unlocks rotation of the locking cam. The locking lever includes a bulge protruding toward the locking cam. A cam contact surface of the locking lever contacts the locking cam when the actuator moves in a drawing-out direction in an intermediate position between the lock position and the unlock position.
