Safety & Compliance

Always ensure your load's continuous current does not exceed 15 A. Follow all local electrical codes when installing high-voltage switching equipment. For guidance on electrical safety standards, visit the U.S. Consumer Product Safety Commission (CPSC) or refer to OSHA's Electrical Safety guidelines.

Frequently Asked Questions

Q: What is the actual rated current for continuous loads on this 433MHz relay switch?

A: Although the relay is labelled 30 A, that figure represents the peak (inrush) current capacity. For continuous operation — such as running a water pump or motor — your load should draw no more than 15 A at 110 VAC or 240 VAC. Always size your circuit accordingly to avoid overheating.

Q: Can I pair more than one remote transmitter with the 433MHz receiver?

A: Yes. The receiver uses a learning-code system, so you can pair multiple 433 MHz transmitters. It is also compatible with additional 315 MHz remote controllers, giving you flexible multi-remote setups for your home or workshop.

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

A: The transmitter has a range of up to 100 metres in an open field. Walls, metal enclosures, and other obstructions will reduce the effective range, so plan your installation with line-of-sight in mind where possible.

Q: What kind of battery does the remote transmitter use?

A: The transmitter is powered by a single 23A/12V alkaline battery, which is a slim, cylindrical battery commonly available at hardware and electronics stores.
