Actuator of a safety switch and safety switch having such an actuator

Actuator (1) of a safety switch (10) for detecting and locking a specifiable state of an apparatus (2), 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), wherein a recess or hole forming the locking flank (50) is centrally arranged within the at least one winding of the inductor (36) and wherein the actuator (1) has a predetermined breaking point (79) that is arranged between a fastener section (80) and a locking-flank section (44) of the actuator (1) having the locking flank (50) and that the locking-flank section (44) can be separated from the fastener section (80) at the predetermined breaking point (79) when excess tensile force arises in the state of the actuator (1) in which it is locked to the switch element (16).
