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.
还发现触头材料的电弧烧损主要是触点在断开和闭合的过程中，产生电弧或其它放电现象的热效应所造成的。
And also, the electric arc erosion of contact materials is engendered by heat effect of arc and other discharge phenomenon during the open and close of electric contact materials.
传统的抽油机控制柜大都采用继电接触系统，通过机械式触点闭合、断开实现电路导通或断开。
The traditional control cabinet of oil-pumping unit is using continuous electricity contact system through the mechanical touching point by closing and opening to achieve the circuit's "on" and"off".
在对电流波动很敏感的应用中，充气继电器具有低而稳定的泄漏电流，特别是在断开触点间，可以长时间保持很低的泄漏电流。
Gas-filled relays also provide low, stable leakage current in applications sensitive to current fluctuations especially across open contact sets over long periods of time.
电动机和控制电压应连接到一个公用网，从这里，当发生电流断路时，电力开关的触点被断开。
The motor- and control voltage is to be connected to a common network, where the sealing-in of the power contactor is cancelled in case of an interruption of circuit.
