Common Causes Of Short Circuits In Wall Switches

If there is wear or aging in the internal wiring and connecting wires of Wall Switch, the conductor insulation may be damaged, causing unintended contact between the live and neutral wires, thus leading to a short circuit. Current chooses the shortest path, and once this abnormal path forms, it will cause a current surge. System protection devices, such as circuit breakers, will quickly cut off the power supply to deal with the abnormal situation.

During installation, excessively long stripped wires or loosely secured terminals can allow bare wires to move freely inside the wall and may come into contact with other conductors. External environmental factors such as moisture infiltration can also reduce insulation performance, and in humid conditions, current is more likely to deviate from its intended path.
