MJKDZ Touch Switch Module

The MJKDZ Touch Switch Module is a single-key touchpad module designed for touch-based switching in electronics and robotics projects. It provides a touch switch function similar to a single button for circuit control. The module can detect touch through glass and other surfaces. It uses the TTP223 main chip and operates with low power consumption. A mono-color LED indicator is included to show touching.

The module is suitable for DC and AC devices and Arduino projects. It is built as a single touchpad switch for replacing a tactile button switch or direct key. The touchpad and line are tuned for stable touch detection. The module is sensitive to human skin and body touch.
