A recording device (7), for recording the switch state of an electromagnetic switch device (1), comprises a housing (8), in which a plunger (9) is a movably mounted. The plunger (9) may be moved between two mechanical end positions, wherein the end positions of the plunger (9) correspond to the switch states of the electromagnetic switch device (1). A sensor device (14) is arranged in the housing (8) by means of which it may be recorded in which of the end positions the plunger (9) is and from which a corresponding electrical signal (E) may be emitted. The sensor device (14) is designed to be able to record the position of the plunger (9) without contacting the plunger (9).
