ABSTRACT:
A safety switch including a spring-loaded tappet axially displaceably disposed in a switch cover; a switching bridge on the tappet; and an actuator above the tappet. An essentially U-shaped element has a center web and a first and second leg. The element is swivellably disposed in the cover in the area of the center web and the first leg of the element engages the tappet. The second leg is situated above the tappet such that when the actuator has moved in, the second leg reaches behind and engages the actuator in a switch-on position and permits a complete pulling-out of the actuator from the cover only in a switch-off position.
