1-dip touch sensor module tact switch electronic DIY part | Switches

Features:
1. Jog type: the initial state is low level, the touch is high level, and the touch is low level (similar to the touch button function).
2. Low power consumption.
3. Power supply can be 2~5.5V DC.
4. Both front and back can be used as touch surface, which can replace traditional touch buttons.
5. Four M2 screw positioning holes for easy installation.

The module is a capacitive touch-type touch switch module based on a touch detection IC (TTP223B). Normally, the module outputs a low level, and the mode is a low power mode; when the corresponding position is touched with a finger, the module outputs a high level, and the mode switches to a fast mode; when there is no touch for 12 seconds, the mode is switched to a low mode. Power mode. The module can be mounted on the surface of non-metallic materials such as plastic and glass, and a thin piece of paper (non-metal) can be placed on the surface of the module. As long as the touch is correct, it can be hidden in the wall, desktop, etc. button. This module allows you to eliminate the hassle of conventional push buttons.

Action note: Light touch contact type touch sensor, then hold the jog type touch sensor for a long time, then the table lamp can be bright and long.
Control interface: a total of 3 pins (GND, VCC, SIG), GND is ground, VCC is the power supply, SIG is the digital signal output pin.
Power indicator: Green LED, it will light up when it is powered on.
Touch area: The inner area of the icon similar to the fingerprint, which can be triggered by a finger touch.
Positioning hole: 4 M2 screw positioning holes, the hole diameter is 2.2mm, which makes the module easy to install and position, and realize the combination between modules.
