摘要
本文提出用小电流晶闸管与接触器组成组合开关。在接通和关断电路时无电弧，接触器可省去灭弧罩，结构简化。且可用于易燃易爆场合。晶闸管毋须电子触发线路，线路简单，成本低。
A novel combined switch is presented in this paper. By employing small current thyristors, we can make a contactor to switch on or off without electric arc. Since arc deflecting cover can be eliminated in the switch, its structure is simple and the switch can be used in inflammable and explosive environment. The thyristors in the switch do not needed electronic trigger circuit. The combined switch is easy to builtland its cost is low.
