- Momentary: Relay connects while the button is held; disconnects on release.
- Toggle: Press once to connect; press again to disconnect.
- Latching: Press Button A to connect, press Button B to disconnect.
- Time Delay: Relay connects on button press; auto-disconnects after 5s, 10s, or 15s once the button is released.

Frequently Asked Questions
Q: What devices can I control with this RF 433MHz relay receiver switch?
A: This wireless relay receiver switch is compatible with a wide range of 12V DC-powered devices, including garage doors, electric gates, LED lighting systems, and other access control applications. As long as the device operates within the 10A / 110W load rating, it can be controlled wirelessly.
Q: How many remote controls can be paired with this receiver?
A: The receiver supports up to 25 paired remote controls simultaneously. If you attempt to add a 26th remote, the first-paired remote will be automatically removed from memory. To clear all stored codes, press the Learning Button 8 times.
Q: What is the difference between the four working modes?
A: Momentary keeps the relay active only while the button is held. Toggle switches the relay on and off with alternating button presses. Latching uses two separate buttons (A and B) to connect and disconnect. Time Delay automatically disconnects the relay 5, 10, or 15 seconds after the button is released — ideal for timed access control or lighting automation.
Q: What is the wireless range of the remote control?
A: The remote control has an operating distance of up to 50 meters in open space. Walls, metal structures, and other obstructions may reduce this range in real-world environments.
