Abstract: A device for switching a connection according to the state of an apparatus to be monitored, especially a safety switch, includes an actuator having first signaling device preferably be fixed on the apparatus to be monitored. The actuator can be brought into contact with an actuator receiver having a second signaling device and can be detachably held to prevent it from being withdrawn. A signal transfer can be carried out in a contactless manner between the first and the second signaling devices. The actuator and the actuator receiver are engaged in an interlocking manner when touching. The first and second signaling devices are arranged such that signal transfer between the actuator and the actuator receiver is only possible in the position in which they are engaged in an interlocking manner.

Abstract: A safety switch (1, 101) for switching a connection in relation to the status of a device to be monitored. The safety switch (1, 101) utilizes an actuator (2, 102) that that can be inserted into the safety switch (1, 101) from a first side (6, 106) and can be withdrawn from a second side (30, 130). The actuator (2, 102) forms a releasable locking engagement with an actuator receptacle (8, 108) located inside the safety switch (1, 101) to form a signal transfer (14,16). The safety switch (1, 101) also can have an ejector that removes the actuator from the actuator receptacle (8, 108).
