Abstract

The invention relates to an electromagnetic switch apparatus having a magnet system with yoke and armature, the armature of which has switch contact parts lying mutually adjacent transverse to the direction of actuation with a contact support guided in the casing of the switch apparatus, which switch contact parts form normally-open or normally-closed contacts with stationary contact parts, and in which support or entrainment stops are provided for the switch contact parts. <??>The contact supports are guided in the housing with play, so that tilting is possible. With respect to this tilting motion, the free path, that is to say the path which is necessary from the lifting of all normally-closed contacts to the resting of all normally-open contacts, must be set to the normally-closed contact lifting last. <??>In order to keep this free path relatively large, the stops facing the casing walls are located in advance of the middle stops in the direction of motion, so that the free path lost by the tilting is thereby gained again. In this way, the force required can be kept lower in comparison to the conventional design, since it has a favourable effect on the traction curve. <IMAGE>
