ABSTRACT:
An electromagnetic relay comprising an electromagnetic device connectable to a power source, utilized to repel a movable blade and thus separate its movable contact from a fixed contact, driving the blade into another configuration in which it is maintained by a permanent magnet. The current in the energizing circuit of the electromagnetic device flows through the movable contact and through the fixed contact so that when the blade is driven into the second configuration, such energizing circuit is interrupted.
