Abstract
A safety switch for reliably switching off a dangerous device has an actuator which can be moved between a first position and at least one second position. It also has a detector for detecting the actuator in at least one of the said positions. The detector comprises a transponder with an individual transponder identification and a reading unit for reading out the transponder identification. The transponder and the reading unit are arranged relative to one another such that the reading unit is capable of reading out the transponder in the first position of the actuator but not in its second position.
