Item Type: Capacitive Touch LED Dimmer_x000D_ Voltage: 2.4-5V_x000D_ Maximum Output Current: 500MA_x000D_ PCB Size: 33x20mm / 1.3x0.79in_x000D_ Pitch: 16mm / 0.63in_x000D_ Hole Diameter: 2.5mm / 0.1in_x000D_ _x000D_ Instructions:_x000D_ a) Short Touch (touch duration is less than 550ms) _x000D_ Can achieve the ON/OFF control of the light. The initial brightness of the light is fixed at 90% of full brightness._x000D_ b) Long Touch (touch duration is greater than 550ms) _x000D_ Can achieve stepless brightness adjustment of the light. When touch for long time, the brightness of the light gradually increases. If touch time exceeds 3 seconds, the brightness of the light does not change after reaching the maximum brightness. When touch again for long time, the brightness of the light gradually decreases. If touch time exceeds 3 seconds, the brightness of the light does not change after reaching minimum the brightness.
