12×12mm Capacitive Touch Button Module — High-Level Output, 3.3V / 5V (2-Pack)
This 12×12mm capacitive touch button module provides a single touch-sensitive button with a digital HIGH output when touched. Unlike mechanical push buttons, it has no moving parts, no contact bounce, and no mechanical wear. The 11×22mm colored cap (red or black) provides a clear tactile target while the capacitive sensor detects touch through the cap. Compatible with Arduino, ESP32, and any 3.3V or 5V microcontroller via the standard 3-pin interface (VCC, GND, SIG). Supplied as a 2-pack.
