摘要： 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.
摘要翻译：本发明提供一种电磁继电器，其即使在用于中断高电压时也具有长的使用寿命，并且可以小型化。在这种电磁继电器中，电路中断由两个或更多个由单个线圈操作并串联连接的键控电路切断。因此，抑制了每个键控电路产生的电弧量。因此，电磁继电器的使用寿命延长。此外，其合约之间的空间减小，使得电磁继电器小型化。此外，用于熄灭电弧的磁场由电路切断时产生的反电动势或反电动势形成。因此，所产生的电弧熄灭。
