Abstract
The invention relates to an actuator (1) of a safety switch (10) for detecting and locking a specifiable state of an apparatus (2), in particular for detecting and locking the closed state of a safety device of a machine (4) or the like, wherein the actuator (1) has an inductor (36) for a contact-free signal exchange with a reading inductor (38) of a switch element (16) of the safety switch (10), and wherein the actuator (1) has a locking flank (50) on which a lock element (24) of the switch element (16) can be brought into locking contact and the actuator (1) can therefore be locked on the switch element (16), characterized in that the inductor (36) has at least one winding extending around the locking flank (50) or around a recess or hole in the actuator (1) forming the locking flank (50) so that the at least one winding extends around the lock element (24) or around an extension of the lock element (24) in the state in which the actuator (1) is locked to the switch element (16), as well as a safety switch having such an actuator.
