Claim:
1. 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 ).
