Overview Staircase lights for residential and single-family dormitories are generally controlled by switches in layers. When people go up and down the stairs at night, they often turn off the lights because of the inconvenience of turning off the lights. The “changing light” often appears and wastes energy. The self-extinguishing switch is designed to solve the “long light”. When someone goes upstairs and downstairs, push the button, the stairs light is on, and after a delay of 1 to 5 minutes (adjustable delay time), when the person enters the house or the person walks out of the building, the light self-extinguishes and self-extinguishes.
