Abstract: A safety switch (2) with a latching unit (12), by means of which an associated actuator (3) is held in a latched position. The latching unit (12) has an opening (9) and a blocking element. In a latched position, the blocking element projects into the opening (9) and rear-engages an actuator head (8) of the actuator (3), which is in the latched position. The blocking element is held in the latched position by means of a positioning element with a setting force. 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.

Abstract: A safety switch (2) with a latching unit (12), by means of which an associated actuator (3) is held in a latched position. The latching unit (12) has an arrangement of latching jaws (14). Each latching jaw (14) is spring-mounted by means of a spring unit (15). The latching jaws (14) are concentrically arranged and each face one another with a first free end and delimit an insertion opening (A). The latching jaws (14) are held in latched position by the spring forces generated by the spring units (15). The latching jaws (14) can be displaced against the spring forces of the spring unit (15), which serves to enlarge the insertion opening (A).

Abstract: An actuator (3) for a safety switch (2) with an actuator head (8), said actuator head being mounted to a core body (6) by means of a connection element (7). The actuator head (8) has, at least in parts, a larger cross section than the connection element (7). The connection element (7) is rigid in the axial direction. The actuator head (8) is held in a base position by means of the connecting element (7). In this base position, the longitudinal axis of the connection element (7) runs at an angle of inclination to the surface of the core body (6).

Abstract: A safety switch arrangement with a safety switch and an actuator associated with it. Moreover, a locking unit is provided for, by means of which the actuator is locked in a latched position. The safety switch has an auxiliary unlocking unit that has a mechanically actuatable actuating element. An actuation of the actuating element is implemented only with a transmission element as a positioning movement for the locking unit.

Abstract: A safety device with a safety switch and an actuator that is arranged movably relative to said safety switch. A transponder is arranged in the actuator, and a reading unit is arranged in the safety switch. A locking position of the actuator is controlled by the fact that transponder signals of the transponder are detected in the reading unit. The safety switch has a locking element with an influencing element. The actuator has a sensor coupled with the transponder. In the locking position of the actuator the locking element is insertable into a receptacle of the actuator. This effects the locking of the actuator. This locking is controlled in that the influencing element is only within the range of influence of the sensor when the locking element is inserted into the receptacle. Said sensor generates a sensor signal via which the transponder signals sent by the transponder are modified.
