ABSTRACT:
A safety switch including a control head rotatably linked to a casing that encloses an electrical contact assembly. A cylindrical collar of the head, engaged in an opening in the casing, is equipped with an annular groove with which retaining elements cooperate in order to immobilize the head along a predetermined direction. A fixing screw cooperates with re-entrant elements situated on the periphery of the collar in order to lock the head and prevent the head from rotating.
