Mini Touch Sensor Dimmabble Pushbutton Smart Home Switch Controller for DC3.7-24V Closet Hallway LED Strip Switch PCB

TTouch Switch Module - Product Specifications1. Electrical ParametersVoltage: 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 DescriptionExtended 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 & SensitivityPenetrable 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 DimensionsOption A: 15 × 13 × 4 mmOption B: 16.5 × 7.5 × 4 mm5. Application ScopeSuitable 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 PrecautionsPower Supply Check: This module is not suitable for Constant Current drivers or lamps with other integrated circuits (ICs).Current Limit: Do not exceed the maximum rated current of 4A.Wiring: Please pay attention to wiring polarity. Ensure input/output wires are not reversed and that positive (+) and negative (-) terminals are connected correctly.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.
