RF433 Wireless Switch, Battery-Free, Remote Control Wall Switch, Self-Powered, No Wiring, Transmitter for Wall Panel (2-Way Kit), Indoor/Outdoor Waterproof - LIAIKI

Wireless Remote Control: Control your electrical applications with the wall transmitter within the required range.

No WiFi/Battery Required: Thanks to the self-powering function of the wall panel transmitter switch, you can remotely control devices connected to RF433 relay receivers without Wi-Fi or batteries, as long as the switch matches the receiver. Additionally, the toggle push button provides great convenience in your smart home.

Multifunctional Switch: One wall panel remote transmitter switch can control multiple RF433 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 RF433 relay receiver and the wall panel transmitter remote control switch must be of the same type.

Therefore, you cannot purchase a receiver or switch on its own, nor can you use the standalone wall panel transmitter to connect to another type of receiver.
