This module is a capacitive momentary touch switch module based on the touch detection IC (TTP223B). Under normal conditions, the module outputs a low voltage, operating in low power mode.

When you touch the designated area with your finger, the module will output a high voltage, switching to fast mode.

If there is no touch for 12 seconds, the module switches back to low power mode. The module can be installed on non-metallic surfaces such as plastic or glass. Additionally, you can cover the module with a thin layer of paper (non-metallic) until the touch position is correct, allowing the module to function as a hidden button on walls, desks, or other places. This module eliminates the need for conventional mechanical press-type buttons.

Features:

• Low power consumption
• Power supply: 2 ~ 5.5VDC
• This module can replace the traditional touch button
• Four M2 screw positioning holes for easy installation.
  Control Interface: There are 3 pins (GND, VCC, SIG).
  • GND is the ground.
  • VCC is the power supply.
  • SIG is the digital signal output pin.

• Power Indicator: Green LED, which lights up when the power is correctly supplied.
• Touch Area: The area inside the fingerprint-like icon, where a light touch with your finger can trigger the module.
• Positioning Holes: Four M2 screw positioning holes, with a hole diameter of 2.2mm, designed for easy installation and positioning of the module, allowing for the combination
