STRONG SIGNAL - Adopting RF technology, it can penetrate walls, floors, and doors, controlling the receiver from anywhere within a reliable distance. The maximum range can reach 328 feet without obstacles. The learning code offers high security due to the low repetition rate and relearning mode, allowing you to erase the old code and learn a new one when a remote is lost. Wide Application: It is mainly used in lamps, electric doors, windows, gates, industrial control, the security industry, and other fields. NOTE: This is not a potentially free contact that only activates the power supply voltage. Please select the appropriate remote control switch according to your device's voltage. 100-meter remote control distance, easy to work in garden plots and even factories. Simply connect it to the circuit; no complicated settings are required. Ordinary people can complete it. Compact design; it doesn't take up much space. Technical Specifications: Voltage: AC100V-240V Max Load: 30A Working
