RF 433MHz Wireless Light Switch 1/2 Gang Smart Wall Switch
RF 433MHz Wireless Light Switch 1/2 Gang Smart Wall Switch
RF 433MHz Wireless Wall Switch – Smart Remote Control for Lights & Appliances
Take full control of your home, office, or workshop lighting without running new wiring. This RF 433MHz Wireless Light Switch pairs a sleek wall-mounted transmitter with a compact relay receiver to let you toggle lamps, LED lights, fans, pumps, and more — all wirelessly from up to 100 metres away in open space.
Important: The relay controller is an RF Receiver and the wall plate is an RF transmitter only. The wall switch cannot control lights on its own — it must be used together with the included RF relay receiver module.

Frequently Asked Questions
Q: Can I use the RF 433MHz wireless wall switch without the relay receiver?
A: No. The wall switch is an RF transmitter only and cannot directly switch lights or appliances on its own. It must be paired with the RF relay receiver module, which is wired into your lighting or device circuit, to control power.
Q: How many wall switches or remotes can I pair with one receiver?
A: The RF relay receiver supports up to 20 paired remote controls or wall transmitters simultaneously, making it easy to control one circuit from multiple locations.
Q: Is this wireless light switch suitable for outdoor use?
A: Yes. The receiver features an IP65 waterproof rating, making it suitable for outdoor installations such as garden lighting, garage doors, and exterior building lighting, as long as it is mounted appropriately.
Q: What is the difference between Toggle Mode and Momentary Mode?
A: In Toggle Mode, one press turns the device ON and a second press turns it OFF — ideal for standard light switching. In Momentary Mode, the device stays ON only while the button is held down and turns OFF as soon as you release it — useful for gates, buzzers, or timed activations.
