## Description

Touch dimmer switch for LED strips at 12-24V DC, allows on/off and smooth light adjustment by touch, capacitive control with 0-100% range for the desired atmosphere, supports up to 4A, narrow 10 mm design easy to integrate into the profile rail, integrated LED indicating the touch area.
The TD01-A3 dimmer touch module is an easy-to-integrate switch designed to adjust the light intensity for LED lighting systems that operate at low voltages between 12 and 24VDC. This device allows users to turn on/off and adjust brightness with a simple touch, providing a versatile light control solution. The module has an intuitive on/off function, as well as the ability to dim or intensify the light, thus creating the desired atmosphere.
It has a width of 10mm, equivalent to the width of most LED strips used in interior lighting, which makes it easy to integrate itself. Once inserted into the track together with the LED strip, the capacitive switch in the form of an arc will remain tensioned on the light diffuser of the track and will allow you to control the light just by touching the contact area of the arc with the diffuser. The touch can be detected through the thin plastic and the location of the button is revealed by an integrated LED inside the arc (on the PCB).

Installation:
Make sure the power supply is off before installation.
Connect the power supply between 12VDC and 24VDC to the input terminals marked with V+ and V- respecting the polarity (+/-).
Connect the LED strip or light source to the output terminals of the module, LED+ and LED- .
Fix the module in the desired place, taking care to protect it from moisture and excessive heat.
Use:
Tap the sensor once to turn the light on or off.
To adjust the light intensity, keep touching the touch sensor until you reach the desired brightness level.
Release the sensor to lock the brightness at the selected level.
Safety and Maintenance:
Do not cover the dimmer module and ensure good ventilation to avoid overheating.
Do not use the module outside the specified voltage range.
Avoid contact with water or other liquids.
Clean the module with a dry cloth and do not use chemical or abrasive substances for cleaning.
