ABSTRACT:
An electromagnetic relay has a core and yoke that are securely attached to the base of the relay with a high degree of precision so that the operating characteristics of the relay do not vary. To this end, two bosses are provided near the lower edge on the inner surface of a hole in a spool of the relay. The bosses are symmetrical with respect to a center line of the spool.
