TTP223 Self Locking Touch Sensor Module – Capacitive Toggle Switch

The TTP223 Self Locking Touch Sensor Module is a capacitive touch input device designed to replace traditional mechanical toggle switches in electronic systems. It uses a TTP223 IC to detect touch input and provides a stable digital output with toggle (self-locking) functionality. The module operates at low voltage and offers reliable performance with high sensitivity and noise resistance. Its compact design allows easy integration into embedded systems and control panels. Ideal for smart home interfaces, DIY electronics, and human-machine interaction projects.
