•  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.

•  Jog type : the initial state is low , high  touch , do not touch is low ( similar touch of a button feature )

•  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
