Safety switch

Safety switch comprising:

• a) a switch housing including a switch;
• b) a plunger, arranged in the switch housing in a fashion capable of displacement in its longitudinal direction against the force of a spring, for actuating said switch arranged in the switch housing,
• c) a cam plate, which is mounted in the switch housing with an axis of rotation extending at right angles to the longitudinal axis of the plunger, and against whose lateral surface, which forms the control cam, the plunger bears,
• d) a key channel in the switch housing, into which the cam plate projects,
• e) a key which upon being inserted in and upon being withdrawn from the key channel positively rotates the cam plate about its axis of rotation and in so doing switches over the switch,
• f) a self-closed locked device, arranged next to the cam plate and capable of being positively released by means of the key upon insertion into the key channel, for the cam plate, having at least one locking member which can be displaced in a translatory fashion and which engages in a self-closed fashion in its locked position with a receptacle arranged next to the cam plate and can be displaced by the key into the release position,
• g) an actuating member constructed in one piece with the locking member and projects into the key channel in the locked position,
• wherein the part of the actuating member which projects into the key channel in the locked position is connected to the locking member via a material part guided laterally past the axis of rotation.
