9V-24V 3A 30W LED Dimming Control Touch Switch

5-24V LED Light Touch Switch Smart Dimming Capacitive Module delivers reliable solid-state touch control and stepless brightness adjustment for modern low-voltage DC LED lighting systems. This versatile module operates across a broad DC input range of 5V to 24V, allowing direct integration with standard LED strips, accent lamps, and smart furniture installations. Furthermore, its high-sensitivity capacitive touch sensor detects touches through non-metallic overlays such as acrylic, glass, and plastic panels without physical contact wear. Consequently, it eliminates the mechanical failure common to traditional switches while offering seamless short-press ON/OFF switching and long-press stepless dimming. Therefore, designers and DIY enthusiasts can easily incorporate clean, modern interface controls into custom architectural and automotive lighting setups.

Key Features:

• Wide Operating Voltage: Supports input power from 5V to 24V DC, allowing universal pairing with standard 5V USB setups, 12V automotive power, and 24V industrial LED strips.
• Stepless Capacitive Dimming: Provides smooth brightness control via long-press touch action, retaining optimal illumination levels across duty cycles.
• Memory Retention Function: Remembers the last selected brightness level automatically when you power off and turn the light back on.
• High Penetration Sensitivity: Detects user touch through non-metallic barrier materials up to ≈ 3 mm thick without needing physical openings.
• Solid-State Reliability: Replaces mechanical buttons with solid-state circuitry to deliver silent operation and an extended operational lifespan.

Pinout and Wiring:

• VCC+ (VIN+): Connects to the positive terminal of the DC power supply (5V – 24V).
• GND (VIN-): Connects to the negative terminal/common ground of the DC power supply.
• LED+ (VOUT+): Connects directly to the positive anode wire of the LED strip or fixture.
• LED- (VOUT-): Connects directly to the negative cathode wire of the LED strip (switched via low-side MOSFET).
• Note: However, do not reverse the input polarity, as doing so may permanently damage the onboard capacitive driver IC.
