ABSTRACT:
An electromagnetic switching device includes a mechanism to couple the magnet armature with its contact carrier. A plate spring is provided with cylindrical formations in its mid-section as well as on its opposite ends so that the plate spring can bend beyond its elongated state. This prevents the spring tension from being altered by contact with the ends of the opening of the magnet armature and the ends of the supporting slots.
