Abstract
An electromagnetic relay having a three part housing. A first or base housing part positions a magnet coil and a stationary magnet pole piece. A second or front housing part positions springs for positioning the coil in the base part, provides a seat for armature return springs and a guide for an assembly including a magnetic armature. A third or a middle housing part maintains the return springs and armature assembly assembled in the front housing part. The front and middle housing parts have rectangularly shaped confronting surfaces which are spaced so the areas of engagement between the middle housing part and the front part are limited to the areas at the four corners of the front and the middle housing parts. The relay also includes a movable contact actuator that is held captive by a cover for the relay.
