Safety switch

Safety switch (2) with a latching unit (12), by means of which an associated actuator (3) is held in a latched position, characterized in that the latching unit (12) has an opening (9) and a blocking element, wherein in the latched position, the blocking element projects into the opening (9) and an actuator head (8) rear-engages the actuator (3) that is in the latched position;

• that the blocking element is held in the latched position by means of a positioning element with a setting force;
• and that, when the actuator head (8) is inserted into or removed from the opening (9), the actuator head (8) pivots the blocking element out against the setting force wherein the latched position of the actuator (3) is monitored by recording signals from a transponder (11) in the actuator (3) with a reader unit of the safety switch (2), when the actuator (3) is moved into the latched position in the safety switch (2)
• wherein the positioning element is formed by a rocker (14),
• wherein the latching unit (12) is associated with a locking unit (18) by means of which the blocking element is held in the latched position, and
• wherein the locking unit (18) has a hinged armature solenoid (19) that has an electromagnet (20) and an armature (21) that can be pivoted using the electromagnet (20), wherein the armature (21) is brought into a locked position in which the armature (21) blocks the rocker (14).
