Date May 28, 1998A switching device is provided which includes a magnet system having a yoke which is elastically mounted by means of a volute spring. The volute spring permits the yoke to be displaced as far as closure of the magnet system. As a result, it is possible to prevent current overloading of the magnet system coil in the case of a welded break contact of the switching device.
