Safety Switch

Abstract

A safety switch prevents incoincidence of contacts from occurring. The safety switch 1 is structured so as to switch the contact by cooperation of an actuator 3 and a switch bod 2. The switch body 2 includes an operating cam 21 and a locking cam 22 that are adapted to rotate by insertion of the actuator 3, an operating rod 26 that switches the contact according to rotation of the operating cam 21, and a locking lever 29 that is provided movably toward and away from the locking cam 22 such that the locking lever 29 takes a lock position IV in which it locks rotation of the locking cam 22 and an unlock position I in which it unlocks a lock state of the locking cam 22. The locking lever 29 includes a bulge 29f that protrudes toward the locking cam 22 at a portion of its cam contact surface. The cam contact surface is adapted to contact the locking cam 22 when the actuator 3 moves in a drawing-out direction in an intermediate position between the lock position IV and the unlock position I.
