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