Wiring Diagrams
Safety Tip: Turn off the main power supply before performing any wiring to prevent electric shock.
One-Way Switch Wiring
Diagram showing connection of Live (L) and Neutral (N) lines to the switch and lamp for a 1-gang 1-way setup.
Connect the Live (L) line to the 'L' terminal on the switch and the Neutral (N) line to the lamp. The switch connects to the lamp via the 'L1' terminal.
Two-Way Switch Wiring
Diagram showing connection of Live (L) and Neutral (N) lines to the switch and two lamps for a 2-gang 1-way setup.
For two-way switching, one live line is sufficient. Connect the L to L, 2WAY/N to 2WAY/N, and one of the L terminals should be connected to the Live line.
Dimmer Touch Switch Wiring

5. Operating Instructions
Touch Switch Operation (1-Way)
Simply touch the switch panel to turn the lamp on or off. When the lamp is on, the backlight indicator will be red. When the lamp is off, the backlight indicator will be blue.
Two-Way Touch Switch Pairing
1-Gang 2-Way Touch Switch Pairing:
- Long press the Main switch button (connected to the light bulb) for 5 seconds. You will hear a "DI" sound, and the Red and Blue background lights will flash.
- Immediately press the Secondary switch button (without light bulb connected). You will hear a "DI" sound, indicating successful pairing.
2-Gang 2-Way Touch Switch Pairing:
- Long press the Main switch first button (connected to the light bulb) for 5 seconds. You will hear a "DI" sound, and the Red and Blue background lights will flash. Immediately press the Secondary switch first button (without light bulb connected). You will hear a "DI" sound, indicating successful pairing.
- Long press the Main switch second button (connected to the light bulb) for 5 seconds. You will hear a "DI" sound, and the Red and Blue background lights will flash. Immediately press the Secondary switch second button (without light bulb connected). You will hear a "DI" sound, indicating successful pairing.
Unpairing Method for Two-Way Switches
Long press the main switch button for 10 seconds (connected to the light bulb touch switch). You will hear two "DI" sounds, and the Red and Blue background lights will flash. This action releases all communication functions (2-Way) and remote control functions.
Dimmer Touch Switch Operation
- Touch the gang briefly to switch the lamp on/off.
- Hold down the button to gradually dim or brighten the light.
- The dimmer has a memory function and will remember the brightness setting from the last operation.
Notes for Dimmer Switch:
- The dimmer can only be used with dimmable lighting (e.g., incandescent lamps or dimmable spotlights).
- The total load power should be less than 500W. It is normal for the inside of the switch to heat up slightly while the lamp is on.
- The stair switch (2-way) does not have dimming functionality.
Timer Touch Switch Operation
- Touch the gang to switch the lamp on.
- The lamp will turn off automatically after 60 seconds.
- To reset the timer, touch the switch again while it is on. The backlight will flash to indicate that it is resetting for another 60 seconds.
Remote Control Pairing and Usage
Small Remote Synchronizing Instruction:
- Hold a gang of the switch for 5 seconds.
- Release when you hear a "Di" sound.
- Press a button on the remote (e.g., button A).
- A "Di" sound from the switch will indicate that synchronization is completed successfully.
Notes for Remote Control:
- To cancel synchronization, press the gang of the switch for 10 seconds. When you hear two "Di" sounds, synchronization is successfully canceled.
- The remote control battery model is 12V/27A. The battery should be replaced in time. Too much discharge can reduce the range of the remote control.
- The remote control does not support remote scene mode.
Curtain Touch Switch Operation
The curtain touch switch can be used to raise or lower curtains, garage doors, etc. The button on the left of the curtain touch switch will raise the curtain, and the button on the right will lower the curtain.
6. Maintenance
The tempered glass panel is designed to be hard, dustproof, and easy to clean. It resists deformation and fading over time, ensuring durability.
To clean the switch, simply wipe the tempered glass panel with a soft, damp cloth. Avoid using abrasive cleaners or harsh chemicals.
7. Troubleshooting
- Switch not responding after installation: If the power was turned on before connecting the glass panel, the switch might not work properly. Turn off the main power supply, ensure the glass panel is correctly installed, and then turn the power back on.
- Switch not working well: If the switch is not functioning as expected, switch off the main power supply for 1 minute, and then switch it on again. This can often resolve minor issues.
- No neutral line required: This touch switch is designed to operate without a neutral line, simplifying installation in many existing electrical setups.
- Relay clicking sound: A soft clicking sound from the relay when operating the switch is normal and indicates proper function.
- Backlight colors: The backlight is typically blue when the light is off and red when the light is on.
8. User Tips
- This switch features a sensitive touch sensor, providing a responsive user experience.
- The backlight indicator is a helpful feature for locating the switch in the dark.
- The switch is compatible with various lamp types, including energy-saving lamps.
- For installation, standard EU flush mount boxes are generally suitable. However, using a deeper mounting box can provide more space for wiring and a cleaner finish.
