1、Using microwave induction technology, it has two working modes (switch mode and induction mode). When in the sensing mode, when a moving object is detected, the switch signal will automatically switch between on and off. In the switch mode, the switch signal remains in a certain fixed state of on and off. 2、Avoid falling ill caused by touching with hands and elbows, ensuring safety, and the switch is not affected by the color, temperature or reflection from the target. 3、There is an adjustable sensing area of 5‑50 cm, no mechanical wear, durable products and long service life. 4、Can be embedded in the wall, neat (no protruding surface), and easy to clean; because the interior is closed, it is destructive and does not require any adjustment. 5、Mainly used in ultra‑clean rooms, operating rooms, food processing, pharmaceuticals, chemical industry equipment control and other fields, but also convenient for the disabled
