What's in the Box?

• 1 × RF Remote Control Transmitter — pocket-sized, powered by a DC 12V (23A/12V) battery
• 1 × Receiver Module — mounts easily in a panel or enclosure

Transmitter Specifications

• Operating Voltage: DC 12V (23A/12V battery × 1)
• Transmitting Frequency: 433 MHz
• Encoding Type: Fixed Code
• Receiver Sensitivity: > −105 dB
• Transmission Distance: Up to 100 m (open field)
• Dimensions: approx. 55 × 28 × 10 mm

Receiver Specifications

• Operating Voltage: AC 75V – 240V
• Output Voltage: Equal to operating voltage (no step-down)
• Operating Frequency: 433 MHz (learning code — compatible with additional 315 MHz remotes)
• Relay Rated Current: 15A continuous load @ 240VAC or 110VAC
• Peak Relay Marking: 30A (peak only — keep continuous load below 15A)

Frequently Asked Questions

Q: What is the maximum continuous load current this 433MHz relay switch can handle?

A: The relay is rated for a maximum of 15A continuous current at both 110VAC and 240VAC. The "30A" marking on the relay refers to the peak (surge) current only. Always size your load to stay under 15A for safe, long-term operation.

Q: Can I pair additional remote controls with the receiver?

A: Yes! The receiver uses a learning code system, which means you can pair multiple transmitters to a single receiver. You can also use compatible 315 MHz remote controllers in addition to the included 433 MHz transmitter.

Q: How far can the remote control reach?

A: In an open field with no obstructions, the transmitter can reach up to 100 metres (approximately 330 feet). Range may be reduced indoors or in areas with thick walls, metal interference, or other RF signals.

Q: What devices can I control with this wireless remote switch?

A: This switch is suitable for water pumps, electric motors, LED lights, fans, electric valves, and most standard AC-powered appliances operating between AC 75V and 240V, provided the load current does not exceed 15A continuously.
