摘要：
There is provided a switching circuit that opens or short-circuits between a first terminal and a second terminal in accordance with a control signal. The switching circuit includes a plurality of switching devices that is serially connected between the first terminal and the second terminal and each of which is opened or short-circuited in accordance with a provided control voltage, and a plurality of control circuits that is provided one-to-one corresponding to the plurality of switching devices, each of which provides a control voltage according to the control signal to the corresponding switching device, and that opens and short-circuits the plurality of switching devices in synchronization with each other.
摘要（中）：
提供了根据控制信号在第一端子和第二端子之间断开或短路的开关电路。 开关电路包括串联连接在第一端子和第二端子之间的多个开关装置，其中每个开关装置根据所提供的控制电压而断开或短路;以及多个控制电路， 一对应于多个开关装置，每个开关装置根据控制信号向相应的开关装置提供控制电压，并且使多个开关装置彼此同步地打开和短路。
