The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the modules output is low, lower power consumption; When a finger touches the corresponding position, the modules output is high, if not touched for 12 seconds, it switches to low-power mode. Jog type : the initial state is lower , higher touch , do not touch is lower (similar touch of a button feature)
This Module can be installed in such as surface plastic, 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
