Light switch sparking when flipped — Alicante, Valencian Community
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.

Spanish REBT requires boletines eléctricos for all installations signed by a registered instalador autorizado. Many buildings still have outdated aluminum wiring in communal areas from 1970s–1980s construction.
