Key Applications 

• Electronic Instruments: Ideal as a "Select" or "Reset" button for DIY synthesizers or oscilloscopes.
  
• Arduino/ESP32 Projects: Use as a pull-up/pull-down input button for project interrupts.
  
• Warning Systems: Use the Yellow LED to indicate a "Standby" or "Ready" state in industrial panels.
  
• Custom Keyboards/Macro Pads: A heavy-duty alternative for specialized industrial inputs.

Project Evolution

• Prerequisites: If you have used standard plastic tactile buttons on a breadboard, this is your professional upgrade.
  
• Feature Upgrade: The 16mm Yellow Momentary Switch transforms a basic "input" into a rugged, weather-resistant interface. Because it is Probots™ Logic-Safe , the 3-6V LED can be powered directly from your microcontroller's 5V rail or a 1S Li-Po battery without needing extra bulky resistors.
  
• Effort Level: Beginner. Simple soldering and a standard 16mm drill bit are all that's required for a professional-grade mount.

Virtual Technician & Wiring
Pin Mapping (5 Pins):

• Pin "+" and "-": Yellow LED Terminals (3V-6V DC).
• Pin "C" (Common): Ground or VCC depending on your logic.
• Pin "NO" (Normally Open): Connect here if you want the signal to trigger when the button is pressed.
• Pin "NC" (Normally Closed): Connect here if you want the signal to trigger when the button is released.

Required

Frequently Asked Questions (FAQ)

1. What does "Momentary" mean?
   It means the switch is only "on" while you are holding it down. It springs back to "off" when you let go.
2. Can I use this for 12V?
   Yes, but you must use a resistor (approx. 470 ohms) in series with the LED pins to prevent damage.
3. Does the Yellow LED look amber or gold?
   It is a classic warm Yellow, perfect for signaling "Caution" or "Ready" states.
4. Is it truly waterproof?
   Yes, the front is IP67 rated, meaning it can survive rain and splashes, making it great for outdoor use.
5. Can I use this as a PC Power button?
   Yes, PC motherboards require a momentary switch for power and reset triggers.
6. Does it come with a wire harness?
   No, but it features solder lugs. We recommend our 16mm pigtail connector for faster wiring.
7. Is the ring LED always on?
   That depends on your wiring. You can wire it to be always on, or only on when pressed.
8. Can I power the LED from a 3.7V Li-ion battery?
   Yes, the 3-6V range is perfect for single-cell Lithium batteries.
9. What size hole do I need to drill?
   Exactly 16mm. A step-drill bit works best for plastic or metal panels.
10. Is the button flat or raised?
    This version features a slightly raised/high-round head for easier tactile discovery.
11. Can it handle 240V AC?
    The contacts can handle AC, but we recommend using it for low-voltage DC signals for safety.
12. What is the current rating for the contacts?
    It is rated for 3A.
13. Will the metal rust?
    No, it is made of stainless steel/nickel-plated brass which is highly corrosion-resistant.
14. How many pins does it have?
    It has 5 pins (2 for the LED, 3 for the switch circuit).
15. Does it include the mounting nut?
    Yes, every switch comes with a hex nut and a rubber O-ring.
16. Can I use this as a doorbell?
    Yes, its momentary action and waterproof rating make it an excellent doorbell button.
17. What happens if I wire the LED backwards?
    Since it is DC, the LED simply won't light up. Just swap the "+" and "-" wires.
18. Can I mount this in a 3D printed case?
    Yes, it is a popular choice for custom 3D printed enclosures.
19. What is the spacing between pins?
    Standard spacing for 16mm series switches; fits most custom pigtails.
20. Is there a latching version?
    Yes, look for the "Latching" version in our catalog if you need the switch to stay on.
