Light switch sparking when flipped? Here's Who to Call
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.
