Description
Overview
A 433MHz wireless relay receiver that switches mains appliances or low-voltage DC loads from a handheld remote. It comes as an AC 85-265V build for direct mains use or a DC 12-72V build for battery and solar systems.
Specifications
- Link: 433MHz RF
- Input: AC 85-265V or DC 12-72V
- Output: relay contact, ON/OFF
- Included: receiver, remote, connector
- Loads: appliances and lamps
Purpose
Lamps and appliances rarely offer a remote input, and pulling a new switch loop through a wall is seldom worth it. This receiver splices into the supply line instead.
Applications
- Ceiling and table lamps
- Fans and small appliances
- 12V and 24V solar lighting
- Shop signage and display lighting
- Pumps in DC systems
How to Use
- Pick the AC 85-265V or DC 12-72V build for your supply; they are distinct products.
- Isolate the circuit at the breaker — the AC version carries mains potential.
- Take supply into the input and route the load through the relay output.
- Pair the remote and prove ON and OFF with the load connected.
- Mount it in a dry enclosure with the antenna clear of metal.
- Stay within the relay contact rating; use a contactor for motors.
