single controllable switch 单可控开关
threshold-controllable switch 阈值可控开关
A controllable switch for interrupting the charging current is controlled when the charging currentexceeds a predetermined charging current threshold.
如 果该充电电流超过一个预给定的充电电流阈值，那么一个可控开关就被 控制以断开该充电电流。
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。
In fountain control system, the controllable silicon is used as power switch unit with the control principle of monolithic processor, which cannot run for a long time.
在喷泉控制系统中，采用单片机控制原理，以可控硅作为功率开关元件，由于可控硅承受过电压、过电流的能力较差，因而不能长时间运行。
