电灯延时开关设计原理

The principle of light delay switch designing

电灯延时开关已在公共场所起到很大节电的作用,但其工作原理介绍不多见。本文详细介绍了开关延时主电路、二线式开关的电源电路以及三种延时开关的设计原理。可对延时开关的设计、调试等起参考作用。

The light delay switch plays a significant role in energy-saving in public places, yet the introduction of its working principle is rare.The principle of main circuit of delay switch,power supply circuit of two-wire switch and three kind delay switches are discussed detailedly in thispaper.It is a reference for designing and debugging of delay switch.
