12V 3A Touch Sensor Switch with Dimmer for Mirror Light
12V 3A Touch Sensor Switch with Dimmer for Mirror Light
This is a 12V DC touch sensor switch module with integrated dimming, designed for controlling LED mirror lights, strip lights, and other low‑voltage loads up to 3 amps. It turns on/off and adjusts brightness with a simple touch, making it ideal for bathroom mirrors, vanity lights, and under‑cabinet lighting where a sleek, button‑free interface is desired. The switch includes a memory function that recalls the last brightness level when powered on.

Compatibility
This switch works with any 12V DC load up to 3A, including LED strips, LED bulbs, and small incandescent lamps. It pairs seamlessly with standard 12V power supplies and is often used with aluminum‑backed LED strips for mirror frames. It does not require a microcontroller and functions as a standalone switch, but it can be integrated into larger automation systems via its touch input line.
Wiring Notes
Connect the 12V DC power supply to the input terminals, the load (LED strip or bulb) to the output terminals, and attach a conductive surface (e.g., a metal plate or copper tape) to the touch wire. Keep the touch wire length under 1 meter and avoid routing it parallel to power wires to prevent false triggering. The total load must not exceed 3A; for higher currents, use a relay or MOSFET driver.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino or Raspberry Pi?
Yes, the touch input can be read by a microcontroller for custom automation, but the switch functions stand‑alone without any coding. The output is 12V, so additional circuitry is needed to interface with 5V or 3.3V logic.
How do I adjust the dimming level?
Tap to turn on/off. Touch and hold to increase or decrease brightness. Release when the desired level is reached. The switch remembers the last setting even after power loss.
Can I use this with a 5V LED strip?
No, the switch operates at 12V DC. For 5V strips, you would need a 12V power supply and a step‑down converter, but this is not recommended. It is best used with 12V loads.
