Arcade machines rely on robust electrical systems to deliver uninterrupted gameplay, and current limiting is a critical safety feature to prevent circuit damage. The most common types include fuses, which are sacrificial devices that break the circuit during overcurrent events. Resistors are also widely used to limit current flow by dissipating excess energy as heat. Additionally, circuit breakers offer resettable protection by tripping when abnormal current is detected. Thermal protection devices, such as thermal cut-offs, activate when temperatures exceed safe limits, safeguarding components from overheating. These methods collectively ensure the longevity and safety of arcade machine operations.
