Wall Switches Are Susceptible To The Risk Of Prolonged Overload.

For Wall Switch in home or commercial environments, overload is not an isolated phenomenon. For example, frequent circuit breaker tripping or abnormal overheating of the switch cover may indicate excessive circuit load. Prolonged overload can lead to loosening of internal switch contacts, fatigue of metal components, discoloration or micro-cracks in the plastic casing. The cumulative effects of these changes differ from traditional short circuits; it is a gradual process of wear and tear.

Furthermore, if the wiring of a wall switch frequently operates under high load conditions, the insulation performance deteriorates due to heat, potentially accelerating wire aging and even causing short circuits.
