Wireless 433 MHz 12 V Relay Switch
This single-channel receiver module operates on a 433 MHz frequency with a 12 V DC supply. It provides wireless on/off control for connected loads using the included RF transmitter. The unit suits hobbyists and installers adding remote switching to lighting, automation or experimental circuits.
Not for multi-channel or mains-voltage projects
Builders who need more than one switched output cannot use this single-channel module. The design is limited to low-voltage DC control at 12 V and does not switch AC mains directly. Users requiring higher voltage isolation or multiple independent relays must select a different device.
Highlights
- 433 MHz wireless control for flexible placement
- 12 V DC operation matches common power supplies
- Single-channel relay switches one device reliably
- Universal module works with standard RF transmitters

Questions about this item
What does the 12 V rating mean when the module is installed in a circuit?
The module requires a 12 V DC power source to operate its relay and RF circuitry.
What does the 433 MHz frequency cap in real use?
The 433 MHz band limits the remote to line-of-sight range and penetration through a few walls, typical for simple on/off switching.
