ABSTRACT:
A low cost electromagnet assembly for a relay. The assembly includes an I-shaped stationary magnet that extends through a passage in a magnet coil and a U-shaped armature assembly with the armature assembly. The armature assembly includes a molded armature guide having projections on a rear wall of the guide arranged to actuate a plurality of switch plungers, side walls extending from the rear wall defining a cavity and an opening in the rear wall exposing a portion of the cavity at the rear wall side of the guide. The assembly also includes the U-shaped armature having a body portion positioned in the cavity and an elastomeric pad position between the armature body portion and the rear wall and a conical spring between the body and guide for absorbing shock created when the electromagnet is deenergized.
