Light switch sparking when flipped — Valencia, 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.
Waarom dit veel voorkomt in Valencia
Many of Valencia's pre-1990 buildings still carry aluminum or outdated copper wiring that does not meet current REBT standards, and electrical panels frequently lack residual-current devices (RCDs) required since 2002. The city's aggressive short-term rental growth has driven numerous unauthorized apartment conversions where electrical capacity was not upgraded, creating overloaded circuits. GVA boletines (completion certificates) are required after any installation work, and inspections by an Organismo de Control Autorizado (OCA) are mandatory for certain categories.
