You can replace a simple light switch yourself if you fully turn off the breaker and verify the circuit is dead. If the switch is part of a 3‑way/dimmer, shows heat damage, or wiring looks unusual, stop and call a pro.
Quick steps:
- Turn off the correct breaker and label it.
- Verify power is off with a non‑contact tester.
- Take a photo of wire positions.
- Move wires to the same terminals on the new switch and tighten.
- Reinstall, restore power, and test.
