  • Patent number: 4658226
    Abstract: An electromagnetic relay includes a moving block assembly which is selectively attracted by the energization of the electromagnet in the relay and moves in a direction perpendicular to the axis of an iron core within the electromagnet, thus actuating a movable contact support. The moving block and the movable contact support slide together, thus preventing wobbling of the movable block assembly within the relay.
    Type: Grant
