Frequently Asked Questions

Q: What is the actual rated current load for this 30A wireless relay switch?

A: Although the relay is labelled 30A, this refers to the peak current only. For continuous safe operation, your connected load (water pump, motor, LED, fan, etc.) should draw no more than 15A at 240VAC or 110VAC. Always size your circuit accordingly.

Q: Can I use this 433MHz remote switch with multiple transmitters?

A: Yes! The receiver uses learning code technology, which means you can pair additional 433MHz transmitters to the same receiver. You can also clear all paired codes by holding the Learning Button for 8 seconds and start fresh.

Q: What voltage systems is this wireless remote control switch compatible with?

A: This switch is highly versatile — it supports AC 75V to 220V and DC 9V to 72V, making it suitable for standard household mains power as well as battery-powered or solar DC setups for pumps, motors, and LED lighting.

Q: How far away can I operate this remote control switch?

A: The 433MHz RF transmitter has a range of up to 100 metres in an open field. Range may be reduced by walls, metal structures, or other RF interference in indoor or obstructed environments.
