  • Patent number: 6853275
    Abstract: The present invention provides an electromagnetic relay that has a long service life, even when being used for interrupting high voltage, and that can be miniaturized. In this electromagnetic relay, the circuit interruption is cut-off by two or more keying circuits, which are operated by a single coil and connected in series. Thus, an amount of generated arc per keying circuit is suppressed. Consequently, the service life of the electromagnetic relay is lengthened. Moreover, the space between the contracts thereof is reduced, so that the electromagnetic relay is miniaturized. Additionally, a magnetic field for extinguishing arc is formed by a back or counter electromotive force generated when the circuit is cut-off. Thus, the generated arc is extinguished.
