Touch Switch Module – Product Specifications

1. Electrical Parameters

• Voltage: DC 3.7V / 5V / 12V / 24V (Constant Voltage only).

• Incompatibility Note: Not suitable for Constant Current power supplies with an output of 10V~30V.

• Current: Maximum 4A.

2. Functional Description

• Extended Sensing: The touch sensor wire can be extended up to 20cm.

• Switch Control: Short press to turn the light ON or OFF.

• Dimming: Stepless dimming function (long press to adjust brightness).

• Memory Function: Remembers the last brightness setting after power-off.

3. Isolation Medium & Sensitivity

• Penetrable Materials: Paper, Acrylic, Plastic, Glass, and Mirror (note: coating must be removed at the touch area).

• Metal Surfaces: Iron/Steel materials are only detectable on small surface areas; large metal housings require an installation hole.

• Sensitivity Rule: Sensing distance varies by medium thickness. Generally, the thinner the material, the better the sensitivity.

4. Physical Dimensions

• Option A: 15 × 13 × 4 mm

• Option B: 16.5 × 7.5 × 4 mm

5. Application Scope

Suitable for various low-voltage constant voltage devices, including:

LED desk lamps, 3D night lights, rattan ball lights, copper wire lights, cool lights, plant lights, photo frame lights, low-voltage light strips, light bars, and LED light boards/strings.

6. Installation Precautions

1. Power Supply Check: This module is not suitable for Constant Current drivers or lamps with other integrated circuits (ICs).

2. Current Limit: Do not exceed the maximum rated current of 4A.

3. Wiring: Please pay attention to wiring polarity. Ensure input/output wires are not reversed and that positive (+) and negative (-) terminals are connected correctly.

4. Material Warning: If the module works during testing but fails after installation, it is usually due to a large-area iron shell (shielding effect). In such cases, an installation hole is required, or the sensitivity needs to be adjusted separately.
