ABSTRACT:
A polarized relay in which the poles of an electromagnet project toward an armature on either side of a pivot support which allows the armature to pivot toward one pole or the other. A pair of permanent magnets each share one pole respectively with the poles of the electromagnet. The other pole of each permanent magnet has a surface extending on either side of the shared pole so as to have a portion closer to the pivot and a portion further away from the pivot relative to the shared pole.
