433MHz RF Wireless Relay Receiver with 2 On/Off Remote Controls for 12-72V DC

433MHz RF Wireless Relay Switch Kit - Receiver with 2 On/Off Remote Controls for 12V-72V DC LED Lights, Fans, Motors and Pumps

Control your DC-powered devices wirelessly with this 433MHz RF relay switch kit, designed for convenient remote on/off operation across a wide range of applications. Suitable for 12V-72V systems, it can be used with LED lighting, fans, motors, pumps, and selected security or automation setups. The included receiver and two remote controls give you flexible operation for home projects, workshops, garages, gates, and equipment control.

With four working modes - momentary, self-locking, interlocking, and delay - the switch can be adapted to different tasks, from simple light switching to more advanced control logic. The 433MHz RF signal provides stable operation up to 50 m in open conditions and can pass through walls, doors, and floors more effectively than infrared-based remotes.

Why this relay kit is perfect to buy
This kit is a practical choice if you want simple wireless control without relying on WiFi or apps. The broad 12V-72V DC compatibility makes it useful across many DIY and technical setups, while the four operation modes give you more flexibility than a basic on/off switch. With two remotes included, it's also convenient for shared use or keeping one spare controller ready.

Interesting facts about RF relay switches
- RF remotes usually work better than infrared remotes when the receiver is not in direct line of sight.
- Interlocking mode is often used in motor and automation control to help prevent conflicting commands.
- 433MHz is popular in remote control systems because it offers a good balance of range, simplicity, and low power use.

Good to know
Always match the relay s wiring and your device voltage correctly before installation. For motors, pumps, or higher-load equipment, check that the switch and connected circuit are rated appropriately for the actual current draw.
