（详情提供中英文描述）
中文描述：
模块特点如下：
点动型：初态为低电平，触摸为高电平，不触摸为低电平(类似轻触按键功能)
低功耗
供电电源可为2~5.5V DC
正反面均可作为触摸面，可替代传统的轻触按键
4个M2螺丝定位孔，便于安装
动作注释：先轻触点动型触摸传感器，再稍长时间按住点动型触摸传感器，则可实现台灯闪亮与长亮；
控制接口：共3个引脚（GND、VCC、SIG），GND为地，VCC为供电电源，SIG为数字信号输出脚；
电源指示灯：绿色LED，上电正确即发亮；
触摸区域：类似指纹的图标内部区域，手指轻轻触摸即可触发。
定位孔：4个M2螺丝定位孔，孔径为2.2mm，使模块便于安装定位，实现模块间组合；
英文描述：
Capacitive type touch jog switch module The module is based on a touch detection IC (TTP223B)'s. Under normal conditions, the module output low, low-power mode to mode; touch of a finger when the corresponding position, the module will output high, the mode is switched to fast mode; when for 12 seconds without touching, the mode and switch to low power mode. Module can be installed in such as plastic, glass surface 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, and other parts of the desktop button. This module allows you to remove the troubles of conventional push-type buttons.
Module features are as follows:
Jog type: the initial state is low, high touch, do not touch is low (similar touch of a button feature)
Low power consumption
Power supply for 2 ~ 5.5V DC
Touch surface can be used as positive and negative, can replace the traditional touch of a button
4 M2 screws positioning holes for easy installation
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;
