Precise compatibility Compatible with Arduino, Raspberry Pi, ESP32, STM32, and other microcontrollers. Ideal for breadboard and prototyping use. Functional replacement Suitable for momentary digital input control such as reset, start/stop, trigger signal, or user interface input. Durable construction 6x6 mm tactile switch mounted on a quality PCB base. Provides good tactile feedback and long mechanical life. Stable performance Bounce mechanical operation with stable signal output and minimal contact jitter. Use scenarios Reset button on a microcontroller development board (Arduino, Raspberry Pi, ESP32, STM32, etc.) to initiate a controlled reset sequence. Start/stop control for a small timing circuit or motor driver in a prototype project. Trigger input or user interface control in a breadboardbased system or handheld prototype. Notes Designed to deliver reliable momentary input in prototyping and development environments, with a compact 6x6 mm size and a durable PCBbased mounting option.
