The moment you release it, the switch returns to its default state. This makes momentary micro switches perfect for trigger-based inputs in robotics, limit sensing, and interactive DIY electronics projects.\u003c\/p\u003e\n\u003ch4\u003eQ: What are the three pins (C, NO, NC) on these miniature switches?\u003c\/h4\u003e\n\u003cp\u003eA: The three pins are Common (C), Normally Open (NO), and Normally Closed (NC). Use C and NO when you need the circuit to close only when pressed; use C and NC when you need the circuit to open when pressed. This flexibility makes these 3-pin micro switches suitable for a wide range of wiring configurations.\u003c\/p\u003e\n\u003ch4\u003eQ: Are these micro switches compatible with Arduino or Raspberry Pi projects?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! These miniature micro switches are widely used in Arduino, Raspberry Pi, and other microcontroller builds. They work well as limit switches, bump sensors, or user input buttons in hobby circuits and DIY electronics projects.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
