It is not intended for motors or inductive loads without proper protection circuits.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I pair the keyfob remote control with the relay module?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What are the different working modes and when should I use them?\u003c\/h4\u003e\n\u003cp\u003eA: The module supports four working modes: \u003cstrong\u003eInching\u003c\/strong\u003e (output activates briefly then resets — great for momentary triggers), \u003cstrong\u003eSelf-locking\u003c\/strong\u003e (toggle ON\/OFF with each press — ideal for lights), \u003cstrong\u003eInterlocking\u003c\/strong\u003e (one button ON, another button OFF — useful for two-circuit setups), and \u003cstrong\u003eDelay\u003c\/strong\u003e (output stays ON for a set duration).

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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this relay switch compatible with both US and European voltage systems?\u003c\/h4\u003e\n\u003cp\u003eA: Yes.
