ABSTRACT:
An electromagnetic relay is provided in which the housing therefor is divided into two space areas, namely, one for the contacts, which is sealed off from a coil space area. The contact space is substantially sealed from the coil winding by having the carrier for the movable armature, the movable contacts and the stationary contacts on one side of a base body, and the coil on the other side. The contact area is provided by the base body and a protective cap. Stationary contact terminals are embedded in the wall of the base body. Spring biased movable contacts are mounted in the contact space. The protective cap closely adjoins the base body. The coil has a ferromagnetic core which at opposite ends of the coil have uprising flanges which form pole shoes. These flanges extend through openings in the base body in proximity to the armature. A permanent magnet means is also located in the contact space area in proximity to the pole shoes so when the coil is energized the carrier is shifted from one position to another to open and close switch contacts. The flanges are sealed to the base body and act as the supporting means for the coil.
