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.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e12V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMax Load Current\u003c\/td\u003e\n\u003ctd\u003e3A (36W at 12V)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimming Method\u003c\/td\u003e\n\u003ctd\u003ePWM, continuous touch hold\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eTouch Sensor Type\u003c\/td\u003e\n\u003ctd\u003eCapacitive, single‑channel\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eStandby Current\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;5mA\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e35mm x 20mm x 8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eLED mirror light with touch dimming for bathrooms or dressing rooms\u003c\/li\u003e\n  \u003cli\u003eUnder‑cabinet kitchen lighting controlled by a touch pad\u003c\/li\u003e\n  \u003cli\u003eWardrobe or closet light that brightens on touch\u003c\/li\u003e\n  \u003cli\u003eDisplay case or shelf lighting with adjustable brightness\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect 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.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery 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.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino or Raspberry Pi?\u003c\/summary\u003e\u003cp\u003eYes, 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.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow do I adjust the dimming level?\u003c\/summary\u003e\u003cp\u003eTap 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.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan I use this with a 5V LED strip?\u003c\/summary\u003e\u003cp\u003eNo, 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.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
