Wholesale TTP223B Touch Sensor Module - 3V-5V Capacitive Touch Switch Board with Momentary/Toggle Mode - Bulk Electronic Components

The features of the module are as follows: 
Pulse-type: Initial state is low level, touch is high level, no touch is low level (similar to the function of a soft-touch button) 
Low power consumption

The power supply can be 2 to 5.5 volts DC. 
Both the front and back surfaces can serve as touch surfaces, replacing the traditional touch-sensitive buttons. 
Four M2 screw positioning holes for easy installation 


Action annotation: First, lightly touch the moving-type touch sensor, and then hold it for a longer period of time. This will enable the desk lamp to light up.

Control interface: There are 3 pins in total (GND, VCC, SIG). GND is the ground, VCC is the power supply, and SIG is the digital signal output pin. 
Power indicator light: Green LED, it will light up when the power is correctly turned on.
