Why Are Wall Switches So Prone To Short Circuits?

In everyday electrical systems, wall switches, directly responsible for switching circuits on and off, are frequently exposed to external factors, making short circuits common. Wall Switch The internal metal contacts, wire connection points and insulation layer may wear or be damaged during frequent operation, causing abnormal current paths and resulting in short circuits.

Common causes of short circuits in wall switches include wire insulation wear, loose connections, or exposed conductors coming into contact with other conductors during wiring. These issues can cause live parts to come into contact, creating a low-impedance path. Moisture infiltration and dust accumulation near the installation location can also weaken insulation, increasing the likelihood of current deviating from its intended path and resulting in a short circuit.

Once a short circuit occurs, the instantaneous current surges dramatically, triggering circuit breakers and potentially causing localized overheating and insulation failure, posing a fire hazard.
