Non-contact Capacitive Touch Sensor Switch Module DC 3V-30V 2A Description: The touch sensor switch module, the back of the circuit board is touch-sensitive surfaces, with high sensitivity, the maximum sensing distance can reach 8mm, the working voltage supports the range of 3V-30V, and the maximum working current can reach 2A. Suitable for LED light control, support for external relays, power switches, etc., low dropout design output voltage = input voltage. Small size, very convenient to stick on the surface of glass, plastic, rubber, acrylic, ceramics and other media. The front of the circuit board is electronic components, and the back is the touch surface. The maximum sensing distance is 8mm . Board Size: Round diameter 2.0CM Working Voltage: DC 3V-30V Working Current: 0-2A Standby Current within 5V, about 2 microamps Working Mode: Support latch/jog (the default state is latch, press once to turn on / press again to turn into standby) Power-on State: Support power-on Boot up/standby (the default state is power-on off state) In Power-on State, the Output voltage = power supply voltage; and the output voltage = 0V in standby state The led light is on in the power-on state; the led light is off in the standby state. _x000D_
