20PCS TTP223 Capacitive Touch Switch Sensor Module 2.5-5.5V Self-Locking TTL But

20PCS TTP223 CAPACITIVE TOUCH SWITCH MODULE 2.5V–5.5V • SELF-LOCKING • TTL OUTPUT • TOUCH SENSOR COMPACT TOUCH BUTTON FOR DIY ELECTRONICS

Product Overview ```

This pack includes 20 TTP223 capacitive touch switch modules. The compact sensor board allows a simple touch to be used as an electronic button input without requiring a traditional mechanical push switch.

The module operates from 2.5V to 5.5V and provides a TTL-level digital output. Configuration pads allow different trigger behaviors, including momentary (no-lock) and self-locking operation.

With its small size and low weight, the module is suitable for Arduino, microcontroller, automation, DIY electronics, control panels and touch-sensitive projects.
