FREQUENTLY ASKED QUESTIONS (FAQ)

1. Is this a latching or momentary switch? It is a momentary switch; it only stays closed while you are physically pressing it.

2. Does it come with adhesive? Yes, the back of the keypad features a peel-and-stick adhesive layer.

3. What is the pinout? Typically, the center pin and one outer pin form the switch contact; use a multimeter to verify for your specific project.

4. Can I use this with an Arduino? Yes, it is perfectly suited for use as a digital input on microcontrollers.

5. Is it waterproof? The top surface is dust and splash-resistant, but the cable connector must be protected from moisture.

6. How long is the ribbon cable? The cable is approximately 80mm to 100mm long.

7. Can the ribbon cable be shortened? It is not recommended as it may damage the internal conductive traces.

8. What is the button made of? It is a textured plastic dome integrated into the PET membrane layer.

9. What happens if I bend the ribbon cable too sharply? Excessive bending can crack the printed silver traces, causing the switch to fail.

10. Does it provide tactile feedback? Yes, it has a physical "click" feel when pressed.

11. Can I use this for high-voltage AC? No, this is intended for low-voltage DC logic signals only.

12. What is the connector pitch? It uses a standard 2.54mm (0.1 inch) pitch.

13. Is the button "Red" as shown? Yes, the active area is clearly marked with a red tactile dome.

14. How thick is the switch? The membrane itself is typically less than 1mm thick.

15. Can I mount it on a curved surface? It can handle slight curves, but mounting on sharp angles may cause the internal contacts to trigger falsely.

16. How many pins are active? Although it has a 3-pin connector, usually only two pins are used for the switch circuit.

17. What is the maximum current? It is rated for signal-level currents, typically up to 100mA.

18. Can I clean the surface? Yes, the top can be wiped with a damp cloth or a small amount of isopropyl alcohol.

19. Will the adhesive stick to metal? Yes, the industrial adhesive bonds well to metal, plastic, and glass.

20. Is it suitable for outdoor use? It is better suited for indoor use or protected enclosures due to UV and humidity sensitivity over time.
