Abstract

There is disclosed a safety switch for generating an enable signal as a function of the position of a moveable guard door. The safety switch comprises a door part and a frame part. The door part has an activator, which can be displaced between a first and a second position. The frame part has a cutout, in which the activator can engage in the second position. A locking element is arranged on the door part in order to lock the activator in the second position. A sensor is designed to detect at least one of the positions of the activator in order to generate the enable signal as a function thereof.
