Wireless Switch, Battery-Free, Wall-Mounted Remote Control, Self-Powered, No Wiring Required, Transmitter for Wall Panel (2-Way Kit), Indoor/Outdoor Waterproof

Wireless Remote Control: Control your electrical applications with the wall transmitter within the required range. Multifunctional Switch: One wall panel remote transmitter switch can control multiple relay receivers, and multiple wall panel remote transmitter switches can also control one RF relay receiver simultaneously. Mount the switch using the included double-sided adhesive. Caution: The relay receiver and the wall panel remote transmitter switch must be used with the same type of receiver. Therefore, you cannot purchase a receiver or switch separately, nor can you use the standalone wall panel transmitter to connect to a different type of receiver.
