另一半是活动铁芯，构造和固定铁芯一样，用以带动主接点和接点的闭合断开。
20A以上的接触器加有灭弧罩，利用电路断开时产生的电磁力，快速拉断电弧，保护接点。
接触器可高频率操作，做为电源开启与切断控制时﹐高操作频率可达每小时1200次。
接触器的使用寿命很高，机械寿命通常为数百万次至一千万次，电寿命一般则为数十万次至数百万次。

电路的装置，所以经常运用于电动机做为控制对象﹐也可用作控制工厂设备﹑电热器﹑工作母机和各样电力机组等电力负载，接触器不仅能接通和切断电路，而且还具有低电压释放保护作用。接触器控制容量大，适用于频繁操作和远距离控制,是自动控制系统中的重要元件之一。
在工业电气中，接触器的型号很多，工作电流在5A-1000A的不等，其用处相当广泛
