Arcade game manufacturers prioritize button microswitch durability to withstand millions of presses in high-traffic environments. They employ rigorous testing methods, including:

1. Automated Press Testing – Machines simulate rapid, repeated button presses (often 1+ million cycles) to mimic years of arcade use.

2. Environmental Stress Tests – Buttons are exposed to extreme temperatures, humidity, and dust to ensure performance in real-world conditions.

3. Force Measurement – Engineers calibrate switches to maintain consistent actuation force over time, preventing "mushy" or unresponsive buttons.

4. Material Fatigue Analysis – High-speed cameras and sensors track metal contact wear, spring tension, and plastic degradation.

5. Real-World Sampling – Prototypes are installed in active arcades for months to collect data from actual gameplay.

Leading manufacturers like Sanwa and Seimitsu use gold-plated contacts and precision springs to extend microswitch lifespans beyond 5 million presses. Quality testing ensures arcade buttons remain tactile and reliable even after years of heavy use.
