Arcade machines are built for heavy use, but their buttons can fail due to wear and tear or other issues. Here are the most common causes of button failure and how to fix them:

1. Dirt and Debris Buildup

- *Cause:* Dust, food particles, or spilled drinks can clog the button mechanism.

- *Solution:* Clean the buttons regularly with compressed air or a mild cleaning solution. Disassemble and wipe the contacts if necessary.

2. Worn-Out Microswitches

- *Cause:* Frequent pressing can wear out the internal microswitches, leading to unresponsive buttons.

- *Solution:* Replace the microswitches with high-quality replacements. Soldering may be required.

3. Loose or Broken Wiring

- *Cause:* Wires can fray or disconnect over time, causing intermittent or total failure.

- *Solution:* Check the wiring connections and solder any loose wires. Replace damaged cables.

4. Sticky or Jammed Buttons

- *Cause:* Old lubricant drying up or foreign objects blocking movement.

- *Solution:* Apply silicone-based lubricant to the button’s plunger or replace the button entirely.

5. Corroded Contacts

- *Cause:* Moisture or oxidation can corrode the metal contacts inside the button.

- *Solution:* Clean the contacts with isopropyl alcohol or replace the button assembly.

Regular maintenance and timely repairs can extend the lifespan of your arcade machine’s buttons. If issues persist, consider consulting a professional technician for advanced troubleshooting.
