A normal light switch should not suddenly develop a pronounced buzz, crackle, or sizzle. If yours does, don't ignore it.
Start with the light itself
If the fixture uses a dimmer, certain bulb and dimmer combinations can produce audible noise. Don't assume that explains a new or severe sound, though.
Is the switch warm?
Heat, discoloration, odor, or visible damage raises the concern. Stop using the switch if it appears unsafe.
Don't open it while energized
Removing a switch exposes electrical wiring. If the problem isn't resolved by an obvious bulb-related issue, have the switch or circuit evaluated.
When should I act quickly?
Get help promptly when buzzing comes with:
- Burning smell
- Heat
- Sparks
- Flickering
- Crackling
- Repeated breaker trips
