The TTP223 Capacitive Touch Switch Module is a compact touch-sensitive electronic sensor designed to detect finger contact without requiring a traditional mechanical button. Operating with a supply voltage of 2.5V to 5.5V DC, this module provides a convenient touch-control solution for Arduino projects, DIY electronics, and embedded systems.
Based on the TTP223 capacitive touch sensor IC, the module detects changes in capacitance when a finger touches its sensing surface and generates a digital output signal. It is suitable for replacing conventional push buttons in electronic control panels, interactive projects, and touch-operated devices.
The module supports configurable output modes, depending on its PCB configuration. In its default configuration, it typically operates in momentary mode, while toggle or self-locking operation may be available through module-specific solder-jumper settings.
