The module is based on a touch detection IC (TTP223B) that functions as a capacitive touch switch module. In the normal state, the module's output is low, with low power consumption. When a finger touches the corresponding position, the module's output becomes high. If there is no touch for 12 seconds, it switches to low power consumption.

Features:

• Low power consumption
• Powered by 2 ~ 5.5V DC
• Can replace the traditional touch switch
• Four M2 mounting holes for easy installation
