Overview
A 433MHz RF relay switch set: a receiver module with an onboard 10A relay plus a handheld transmitter for ON/OFF control. It runs from DC 5V to 48V and comes in a black or white housing.
Specifications
- Frequency: 433MHz RF
- Input: DC 5V, 12V, 24V, 36V or 48V, by version
- Switching: 10A relay
- Function: ON/OFF from the paired transmitter
- Colours: black, white
Purpose
It adds remote switching without running control cable to a switch position, and the 5V to 48V input lets one family serve breadboard builds and 48V panel gear alike.
Applications
- LED strip and lamp circuits
- Gate and garage triggers
- 12V and 24V pumps and fans
- Cabinet and display-case lighting
- Automotive accessory switching
How to Use
- Order the input variant matching your supply; the five voltages are separate builds.
- Wire DC into the receiver terminals and check polarity twice.
- Loop the load through the relay’s normally-open contacts.
- Code the transmitter, then prove ON and OFF from range.
- Keep load current under 10A and add a contactor for motors.
