1、The optical control switch module is a new type of photoelectric switch designed and manufactured according to the photoelectric conversion characteristics of semiconductor devices. 2、At dusk and dawn, street lights can be turned on and off automatically according to changes in natural light, which is automatically controlled and energy‑saving. 3、The internal control is controlled by a relay, which is compatible with loads of various resistance, inductance and capacitor lights. 4、It can be loaded with electrical equipment such as LED lamps, energy‑saving lamps, fluorescent lamps, incandescent lamps, and exhaust fan lamps. 5、Generally installed in lamps or boxes, it has novel design, reliable installation, small size, light weight, convenient installation and long service life. 6、It is mainly composed of sealed CDs photoresist and integrated circuits. High sensitivity, more convenient to use.
