Dangerous Light Switch Warning Signs
These symptoms mean your switch is failing or your wiring is damaged. Every one of these is a potential fire or shock hazard — don't wait.
Light Switch Sparks
Visible sparks when flipping a switch indicate arcing inside the switch or loose wire connections. Arcing generates extreme heat and can ignite surrounding materials.
Stop using the switch immediately. Call us for emergency replacement.
Burning Smell from Switch
A burning or melting plastic smell near a switch means wiring insulation is overheating. This is an active fire risk happening inside your wall.
Turn off the breaker for that circuit and call us immediately.
Switch Hot to Touch
A warm or hot switch plate means the switch is handling more current than it's rated for, or connections are loose and arcing. Dimmer switches may feel slightly warm — regular switches should not.
Replace with a properly rated switch. We'll check the circuit load.
Buzzing Light Switch
A humming or buzzing switch often indicates a loose connection, an incompatible dimmer, or a switch nearing failure. With dimmers, it can also mean the dimmer isn't compatible with your LED bulbs.
We'll diagnose the cause and install a compatible replacement.
Flickering Light When Switch On
Lights that flicker only when a specific switch is used point to a failing switch, loose wiring at the switch box, or an overloaded circuit sharing too many loads.
We'll test the switch, tighten connections, and check circuit load.
Switch Shocked Me
Getting a shock or tingle when touching a switch means current is leaking to the faceplate — usually from a ground fault, missing ground wire, or damaged insulation inside the box.
Do not touch the switch again. Call us for emergency diagnosis.

Dimmer Switch Not Working or Flickering LEDs?
