《建筑电气》1986年第4期《简易门控开关》一文中介绍的门控开关简单易行,较为方便地实现了暗间厕所照明灯的控制。然而绝大部分厕所为非暗间,即白天无需照明。如果在这种开关的基础上再加一光电控制器,使照明灯在白天不亮(即不受门控),而到了夜晚又恢复门控,则非暗间也能适用。 The door control switch described in “Simple Door Control Switch” in “Building Electric” (4th issue, 1986) is simple and easy to implement, and it is relatively easy to control the darkroom toilet light. However, most toilets are non-dark, meaning there is no need for lighting during the day. If a photoelectric controller is added on the basis of this switch, so that the lights do not light during the day (ie, not subject to gating), and the gating is resumed at night, non-darkness can also be applied.
