摘要:
An electromagnetic switching device is disclosed with an electromagnet and a movable magnet armature, which is mounted in the switching device with a resetting force, which counteracts the closing force, is different than zero in an OPEN position and is formed at least partially by a magnet arrangement with at least one permanent magnet. The magnet arrangement is arranged fixed in position in the switching device outside the magnetic circuit formed from the electromagnet and the magnet armature, and whose resetting force, which acts on the magnet armature, is at a maximum in the OPEN position.
