Exceeding this may damage the relay and create a safety hazard.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I pair multiple transmitters to one receiver, or use one transmitter with multiple receivers?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. Because the receiver uses learning code technology, you can pair multiple 433MHz transmitters to a single receiver. You can also use one transmitter to control several receivers simultaneously, making it perfect for whole-room or multi-device setups.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What's the difference between Momentary, Toggle, and Latched modes on this wireless remote control switch?\u003c\/h4\u003e\n\u003cp\u003eA: \u003cstrong\u003eMomentary\u003c\/strong\u003e means the relay is only ON while you hold the button. \u003cstrong\u003eToggle\u003c\/strong\u003e switches the output ON with one press and OFF with the next. \u003cstrong\u003eLatched\u003c\/strong\u003e keeps the relay ON after a single press and requires a second press to turn it OFF — similar to toggle but with a firmer lock-on behaviour.
