Can you replace a light switch without turning off the power?
If you don’t turn the breaker off, you have current possible at the fixture. This is extremely unsafe as you will (probably) need to remove wire nuts, separate the wires, connect wires, and put on a wire nut without touching the hot wire. If you don’t turn the breaker off, you have current possible at the fixture.
Can a faulty light switch cause a fire?
Answer: It would be unusual, but possible as long as the circuit is hot. The small springs inside the switch gradually go bad, causing resistance and that resistance causes heat, which causes a fire.
Do light switches wear out?
For starters, light switches wear out because of their frequent use. When they wear out, they don’t work or, worse, they give off sparks. A light switch that gives off sparks is a fire and shock hazard and should be replaced immediately. Another reason for replacing a light switch is better functionality.

How do electrical fires start in walls?

Can I replace a light switch with an outlet?
If You Want the Switch and Outlet Independent From One Another. To make this happen, all you have to do is switch the places of the two black wires. So you’ll connect the black hot wire coming from power to either black screw and then connect the black wire coming from the light fixture to the brass screw.
Will a light switch work without a ground?
It is perfectly legal to wire a light switch without the inclusion of a ground. Dimmers will require a ground wire but traditional toggle-type switches will not. Omitting a ground wire on any switch is not recommended.
