Abstract
A polarized electromagnet comprises a generally E-shaped yoke including a pair of outer legs and an intermediate leg therebetween, the three legs being interconnected by a base portion, and a coil wound about the intermediate leg. A generally U-shaped armature comprises a permanent magnet and two pole plates attached to both ends of the permanent magnet. The armature is so positioned that each pole plate extends between the intermediate leg and a respective one of the outer legs of the yoke. The armature may be fitted into a generally U-shaped resin member integrally molded with portions extending outwardly to opposite sides of the pole plates and slidable engaged in guide slots provided in the outer yoke legs. When used in an electromagnetic relay, these projecting portions form actuating members engaging movable contacts of the relay.
