由一根绝缘杆同时开动的三个移动触点断开和连接电路。
Three movable contacts, actuated simultaneously by an insulated rod, open and close the circuit.
释放时间与触动时间是相对应的。它衡量的是从线圈断开激励到触点达到稳定所需的时间，也包括回跳。
Release time is the opposite of actuation time. It is measured from the time power is removed from the coil until the contacts have settled, again including bounce.
在使用中如按钮失灵(按钮松开后吊篮仍然继续上升或下降)、接触器触点粘合等情况，则立即断开总电源开关，停止使用。
If button failure (after button released, the basket still keep rising or falling) or adhesion happens in the process of use, the general power supply should be cut and stop using.
