Can I fix my own light switch safely without an electrician?

Yes, some homeowners can safely replace a simple light switch, only If the circuit is fully de-energized and the wiring is straightforward. We always recomend hiring one of Castle Electric's Licensed electricians, who will find dangerous that the untrained eye would miss. If the switch is warm, buzzing, burnt, or part of a 3-way/4-way circuit, hire a licensed electrician in Quincy, MA.

Quick checks:

• Turn off the correct breaker.
• Verify no power with a non-contact tester.
• Label wires; use the same switch type and rating.
• Stop if wires are damaged or aluminum.
