Setup and Installation

1. Safety Precautions

Ensure power is disconnected before installation.
This device operates on DC12-24V. Do NOT connect directly to 220V AC.
A constant voltage switching power supply is required.
Ensure all connections are secure and insulated.

2. Components Overview

Figure 2: Touch Switch Modules and Control Box. The top two modules are for metal touch sensing, the bottom white box is the control unit.

3. Power Supply Requirements

The TQ-803 and TQ-804 series switches are designed for DC12-24V constant voltage light sources with a maximum power of 50W. It is crucial to use a constant voltage switching power supply to convert your main voltage (e.g., 220V) to the required DC12-24V.

Figure 3: Power Supply and Light Source Compatibility. 220V cannot be directly connected to constant voltage light sources. A constant voltage switching power supply is required.

4. Wiring Instructions

Refer to the specific wiring diagram for your model. Ensure all connections are made correctly to prevent damage to the switch or light source.

Table 1: Wiring Methods by Model
Model	Wiring Method
TQ-803K/S/W/D Series	Power Supply: Connect the red wire to the positive (+) terminal and the black wire to the negative (-) terminal of your DC12-24V power supply. Light Source: Connect the red wire to the positive (+) terminal and the blue wire to the negative (-) terminal of your constant voltage light source. Touch Head: The touch head will emit a bright blue light (warm light) when active.
TQ-804K/S/W/D Series	Power Supply: Connect the red wire to the positive (+) terminal and the black wire to the negative (-) terminal of your DC12-24V power supply. Light Source: Connect the red wire to the positive (+) terminal and the blue wire to the negative (-) terminal of your constant voltage light source. Touch Metal Body: Connect the yellow wire to the metal body that will act as the touch sensor. Important: The recommended size for the touch metal body should not exceed 15x15cm. Ensure the touch body and the light source are properly insulated from each other and other conductive parts.

Maintenance

Keep the touch sensor area clean and free from dust or moisture to ensure optimal performance.
Do not use abrasive cleaners or solvents on the switch or touch panel. A soft, dry cloth is sufficient for cleaning.
Ensure proper ventilation around the control unit if it is enclosed.

Troubleshooting

Switch not responding:
- Check if the power supply is connected and providing the correct DC12-24V.
- Verify all wiring connections according to the diagrams (power, light source, touch sensor).
- Ensure the touch sensor area is clean and unobstructed.
- For TQ-804 models, ensure the metal touch body is properly insulated and within the recommended size.
Light not turning on/off:
- Check the light source itself to ensure it is functional.
- Confirm the light source is a constant voltage type and its power consumption does not exceed 50W.
- Recheck wiring to the light source.
Dimming not working:
- Ensure you have a dimmable light source compatible with constant voltage dimming.
- Verify you are using a TQ-803S/W or TQ-804S/W model, as only these models support dimming.

User Tips

Always double-check your voltage requirements. Using the wrong voltage is the most common cause of damage.
For TQ-804 models, experiment with different metal surfaces for the touch sensor to find the best responsiveness, ensuring proper insulation.
When installing in tight spaces, ensure the control unit has adequate airflow to prevent overheating.
