Electro-mechanical switchgear e.g. relay, has armature supported such that armature implements movement with movement component that is directed perpendicular to pole surface, and coil exhibiting component directed perpendicular to surface

摘要

The switchgear has electromagnets (2) with an exciter coil operated with a direct current (4), where the electromagnets contain a core (10) with a pole surface (12). An armature (14) is assigned to the electromagnets for actuating a movable contact (16), where the armature is made of a permanent magnetic material. The armature is supported in such a manner that the armature implements a movement with a movement component that is directed perpendicular to the pole surface. The exciter coil exhibits a component that is directed perpendicular to the pole surface.
