Light switch sparking when flipped — Leiden, South Holland
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.
Why this is common in Leiden
Electricians in Leiden switch between careful upgrades in older (often protected) buildings and standard consumer-unit work, plus the growing wave of EV chargers, heat-pump circuits and solar tie-ins.
