An apparatus () monitors a protective device () of a machine (). The apparatus () has a switch housing () with a switch head () and an actuator (). In the closed state of the protective device (), the actuator interacts with the switch head () with that closed state being signaled. The apparatus () has a tumbler device () with a tumbler element () mounted movably in the apparatus () to lock releasably the closed state. The tumbler device () has a permanent magnet (). The magnetic force fixes the tumbler element () in a first position when the power supply to the apparatus () is switched off to lock the closed state of the protective device (), in a second position with the tumbler device () not locking the closed state.

Apparatus for monitoring the state of a protective device of a machine

An apparatus () for monitoring the state of a protective device () of a machine () in particular is a safety switch for monitoring the closed state of a protective door or the like. The apparatus () has a switch housing () with a switch head () and an actuator (). In the closed state of the protective device (), the actuator interacts with the switch head () and, as a result, the closed state of the protective device () can be signaled. The apparatus () has a tumbler device () with a tumbler element () mounted movably in the apparatus () and by which the closed state of the protective device () can be locked releasably. The tumbler device () has at least one permanent magnet (). By the magnetic force, the tumbler element () can be fixed in a first position when the power supply to the apparatus () is switched off, in which first position the tumbler device () locks the closed state of the protective device (), and/or can be fixed in a second position, in which the tumbler device () does not lock the closed state of the protective device ().

A device () maintains a locked and closed state of a space separating device () in a releasable manner, in particular a protective device of a machine (). The device has a first part () with an opening and a second part (). The parts are movable relative to one another. The opening is at least partially closable. The device () includes a latch () for locking the closed state of the space-separating device (), a holding element () for keeping the latch () in the latched position, and a release element () for releasing the catch of the latch (). The catch of the latch () may be lifted by a rotational movement of the release element () relative to the latch ().
