Lights inbuilding passageway automatically delay turning off
Figure 38 is saving circuit of the building corridor lighting, when people walk into the building corridor, press any buttons, SJ relay closes, delay normally closed point of SJ closes, lamp turns on, and then people start walking, until get indoors, the delay normally closed point opens after a period of closing time, so that the corridor lights automatically turns off. The time delay relay in the circuit uses JS7-44 power-off delay time relay. Coil voltage is 220V. The power-off delay time relay works after the coil gets electricity, and make SJ closes, and breakes in a delay time after the coil being power-off. This method is simple. (View)
