Double Throw Contact是一种集成在双掷开关和钟摆中的触点，可以实现状态多重切换，改变电路状态。它是由两个接触器组成的绝缘设备，可以在电子设备或电气设备中连接或断开电路。

Double throw contact handles are designed to switch electrical circuits in two different directions. That is, when it is used in a single pole double throw (SPDT) switch, it can switch an electrical circuit between two different contact points. This type of application is used to turn on or off an electrical device. For example, the double throw contact could be used to switch the power supply of a motor between two different sources. As a result, when the switch is turned off, the motor could be powered from one source, and when the switch is turned on, the motor could be powered from the other source.

双投触点把手设计用于以两个不同方向切换电路。也就是说，当它用于单位极双投（SPDT）开关时，可以在两个不同的接触点之间切换电路。这种应用可以打开或关闭电子设备。例如，双投触点可以用于在两个不同的电源之间切换电动机的电源。因此，当开关关闭时，电动机可以从一个电源获得动力，当开关打开时，电动机可以从另一个电源获得动力。
