433MHz RF Wireless Remote Control Switch – Relay Receiver & Transmitter

Take Full Control of Your Appliances — Wirelessly

The 433MHz RF Wireless Remote Control Switch gives you the freedom to operate lights, electric doors, automated curtains, and other AC-powered appliances from up to 100 metres away — no app, no Wi-Fi, no complicated setup required. The compact RF relay receiver pairs easily with the included transmitter and supports four versatile trigger modes to suit virtually any automation scenario. Made in China.

Key Features

• Wide Voltage Compatibility: Receiver operates on AC 110V–240V, making it suitable for use in most countries worldwide.
• Long Wireless Range: Up to 100 metres in open-field conditions for reliable, lag-free switching.
• Four Control Modes: Jog (momentary), Self-Locking (toggle), Interlock (two-button A/B), and Auto-Delay (5 / 10 / 15 / 20 seconds) — all programmable via the learning button.
• Simple Code Learning: Program the receiver to recognise your transmitter in seconds with the on-board indicator-guided learning system.
• Relay Rated Contact: 15A / 240VAC continuous (30A peak) — suitable for lamps, small motors, electric door controls, automated curtains, and more.
• Compact Form Factor: Receiver box approx. 65 × 45 × 28 mm; transmitter approx. 55 × 28 × 10 mm — easy to install in tight spaces.
• Fixed & Learning Code: Transmitter uses fixed encoding; receiver uses learning code for flexible compatibility.

Control Mode Guide

1. Jog (Momentary): Relay closes while button is held; disconnects on release.
2. Self-Locking (Toggle): First press closes the relay; second press opens it.
3. Interlock (A/B): Button A closes the relay; Button B opens it.
4. Auto-Delay: Relay closes on button press and automatically disconnects after 5, 10, 15, or 20 seconds (user-selected during code learning).

Code Learning — Step by Step

• Jog: Press learning button once → indicator flashes rapidly → press transmitter button → indicator flashes 3× → done.
• Self-Locking: Press learning button twice → indicator flashes 2× → press transmitter button → indicator flashes 3× → done.
• Interlock: Press learning button 3× → press A button (indicator flashes 3×) → press B button → indicator flashes 3× and goes out → done.
• 5-sec Delay: Press learning button 4× → press transmitter → indicator flashes 3× → done.
• 10-sec Delay: Press 5× → same process as above.
• 15-sec Delay: Press 6× → same process.
• 20-sec Delay: Press 7× → same process.
• Clear All Codes: Hold learning button for 8 seconds until indicator flashes 6× rapidly.

Frequently Asked Questions

Q: What is the maximum continuous load current the RF relay receiver can handle?

A: The relay receiver is rated for a continuous load of 15A at 240VAC or 15A at 110VAC. The "30A" marking refers to the peak surge current only — always ensure your connected appliance draws less than 15A continuously for safe, reliable operation.

Q: Can I pair multiple remote controls with one receiver?

A: Yes. The receiver uses a learning-code system, which means you can program additional 433MHz transmitters to work with the same receiver by repeating the code-learning process for each remote. This makes it easy to control one device from multiple locations.

Q: Does this wireless remote control switch require an internet connection or smartphone app?

A: No. This switch operates entirely via RF (radio frequency) at 433MHz and does not require Wi-Fi, Bluetooth, or any smartphone app. It works as a standalone system, making it highly reliable even in areas with poor connectivity.

Q: How do I clear all previously learned codes from the receiver?

A: Press and hold the learning button on the receiver for approximately 8 seconds without releasing. The indicator light will flash once and then flash 6 times rapidly, confirming that all stored codes have been successfully cleared.
