ABSTRACT:
An electromagnetic relay has low heat transmission from the electromagnetic block to the contacts and a conductive circuit would have low electrical resistance. In the relay, a movable contact terminal is caulked to a yoke with a flat protruding segment between them to act as a spacer to reduce the heat transmission. The relay may also have a movable contact terminal and a movable hinged spring fixed to the yoke of the electromagnetic block. The hinged spring may then be directly electrically connected to the movable contact terminal which is fixed to the yoke to lower the electrical resistance.
