For example, a transistor is a controllable switch, but it is directional between the collector and emitter, and it has interactive control between the base and emitter.

例如，晶体管是可控的开关，但它在集电极和发射极之间是定向的，并且在基极和发射极之间是配合控制的。

Moreover, the collector of switching transistor is also connected to an output end of PG signal directly. The emitter is also connected to an input end of a control signal directly.

此外，该开关晶体管的集电极还直接连至一pg信号输出端，发射极还直接连接至一控制信号输入端。
