Frequently Asked Questions
Q: What does the 3-pin configuration mean on these micro switches?
A: The 3 pins correspond to Common (C), Normally Open (NO), and Normally Closed (NC) terminals. This gives you flexible wiring options — use the NO terminal for a circuit that closes when the button is pressed, or the NC terminal for a circuit that opens on actuation. This makes the 3-pin micro switch highly versatile for limit detection and push button applications.
Q: Are these micro switches compatible with 3D printers and CNC machines?
A: Yes! These 1A 125V AC 3-pin micro switches are a popular choice for 3D printer endstops and CNC axis limit switches. Their compact size and standard pin layout make them easy to install as drop-in replacements or new builds. Buying in a 10-pack ensures you have spares on hand for future projects.
Q: Can I use these switches to repair a computer mouse?
A: Absolutely. These micro switches are commonly used as mouse button replacements. The crisp actuation and compact form factor match the style of switches found in many standard mice. Always verify your mouse's switch specifications before replacing to ensure compatibility with the 1A / 125V AC rating.
