Frequently Asked Questions

Q: What devices can I control with this 433MHz wireless relay switch module?

A: This relay switch is compatible with a wide range of AC-powered devices, including ceiling fans, lamps, light strips, exhaust fans, and other household appliances that operate within the AC 90–265V range and draw up to 3000W (30A). It is not intended for motors or inductive loads without proper protection circuits.

Q: How do I pair the keyfob remote control with the relay module?

A: The relay module uses a Learning Code 1527 system. To pair, briefly press the learning/pairing button on the relay module until the indicator light activates, then press the button on your keyfob within a few seconds. The indicator light will confirm successful pairing. You can pair up to the number of remotes included in your selected bundle.

Q: What are the different working modes and when should I use them?

A: The module supports four working modes: Inching (output activates briefly then resets — great for momentary triggers), Self-locking (toggle ON/OFF with each press — ideal for lights), Interlocking (one button ON, another button OFF — useful for two-circuit setups), and Delay (output stays ON for a set duration). Select the mode that best suits your application.

Q: Can I use multiple remote controls with the same relay switch module?

A: Yes. Depending on the bundle you choose, you can pair up to 5 keyfob remotes to a single relay module. This is ideal for households where multiple family members need independent control of the same device.

Q: Is this relay switch compatible with both US and European voltage systems?

A: Yes. The module supports AC 90V–265V, making it compatible with standard electrical systems in the US (110V/120V), Europe (220V/230V), and most other regions worldwide.
