ABSTRACT:
Relay comprising an electromagnetic coil wound an an insulating bobbin, the central cavity of which encloses a central spring-biased contact actuated by a magnetic armature in response to energization of the coil, to make or break contact with one or more fixed contacts also enclosed. A U-shaped member and heel plate, both of highly magnetically permeable material, surround the coil and complete the magnetic circuit for flux generated by the coil. In one modification a permanent magnet interposed into the cavity aids or repulses the flux generated by the electromagnet, depending on their respective directions. In accordance with another modification the bobbin and the enclosing coil are elongated to include a plurality of sets of contacts which are being simultaneously actuated.
