Light switch sparking when flipped — Madrid, Madrid
A small blue spark inside a switch is normal as contacts close, but visible yellow or white sparks, a popping sound, a burning smell, or a warm faceplate indicate a dangerous fault. Causes include worn-out contacts, loose wire connections, an overloaded circuit, or a failing dimmer. An electrician should inspect the switch, check wiring for scorching or arcing damage, replace the defective device, and verify the circuit load is within safe limits.
Waarom dit veel voorkomt in Madrid
Many pre-1990 Madrid buildings carry undersized wiring that cannot support modern dual heating-and-cooling loads, and panels frequently lack the residual-current devices required since 2002. The combination of winter electric heating and summer AC pushes circuits hard, and any installation work requires a completion certificate filed with the Comunidad de Madrid industry directorate.
