Light switch sparking when flipped — Barcelona, Catalonia
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 Barcelona
Many pre-1990 Eixample and Gràcia buildings still carry undersized or outdated wiring that fails current REBT standards, and panels frequently lack the residual-current devices required since 2002. Lifts retrofitted into stairwells and patios add complex shared electrical infrastructure, and any installation work requires a GVA-equivalent Catalan completion certificate filed through the Generalitat.
