Abstract
An electromagnetic switching device having a magnet system with a magnet yoke and armature, this armature being connected to a contact carrier, which is movably guided in the housing of the switching device and has switching contacts lying one behind the other at right angles to the actuating direction. Together with stationary contacts, these switching contacts form make or break contacts, with supporting or locking stops being provided for switching contacts in the contact carrier. The contact carriers are guided with clearance in the housing, so that a tilting is possible. With regard to this tilting motion, the free path, that is the path which is required from the point where all break contacts are disengaged up to the point where all make contact are brought into contact, must be cut off at the last disengaging break contact. To keep this free path relatively long, the stops are arranged in the contact bridge carrier in a staggered manner.
