Abstract:
An electromagnetic relay switches to conduct and interrupt currents having different magnitudes and flowing though mutually opposite paths via the electromagnetic relay. The relay includes a coil generating a magnetic force and a pair of contact sections opened and closed selectively by the magnetic force. The contact sections comprise a pair of fixed contacts and a pair of movable contacts. Each fixed contacts is held by a pair of conductive fixed holders and is near a tip section of each fixed holder. The movable contacts are fixed to a conductive movable holder and moves toward and away from the fixed holders selectively in response to the magnetic force. The relay further includes two arc-extinguishing magnet members adjacent to the contact sections such that, the arc generated by interrupting one current having a magnitude larger than the other current is extended toward the tip section at each contact section.
