Description:
100% brand new and high quality
The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption; When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.
Job type: the initial state is low, high touch, do not touch is low ( similar touch of a button feature )
A module can be installed in such as surface plastic, the glass of non-metallic materials
In addition to the thin paper ( non-metallic ) covering the surface of the module, as long as the correct location of the touch, you can make hidden in the walls, desktops and other parts of buttons
Features:
Low power consumption
Power supply for 2 ~ 5.5V DC
Can replace the traditional touch of a button
Four M2 screws positioning holes for easy installation

Touch Sensor Interface :(the last picture show)
-Control Interface : A total of three pins (GND, VCC, SIG), GND to ground , VCC is the power supply , SIG digital signal output pin ;
-Power Indicator: Green LED, power on the right that is shiny ;
-Touch area: Similar to a fingerprint icon inside the area, you can touch the trigger finger.
-Positioning holes: 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install, to achieve inter-module combination ;
