Hi, I'm Nick Marra with CJS Electric. Today, I want to show you how to replace a light switch. This particular light switch is an old type toggle switch and the owner here would like to replace it with this rocker type decor out switch. First thing you need is a screwdriver, flat and Phillips and a voltage tester. And you will also need some needle nose pliers with some good insulated handles. First thing to do is to go to the electrical panel and find the proper circuit that controls the light, check the voltage once you've turned off the breaker, check the voltage between the bare wire and all wires in on the switch. At that point you can disconnect your ground wire and the two wires to the switch. Basically replace the wires with the same wires that came off the switch, it has two screws, attach the one feed if you know which one is the feed to the black wire, to the black screw and the other wire to the other screw. Always remember to attach your bare ground wire to the green screw. Reassemble everything, turn the circuit breaker back on and you should be good to go. I'm Nick Marra and that's how you replace a single pulse switch in a home. Remember where there's a wire there could be a fire so make the right hire, Nick Marra: cjselectric7.com. Thank you.
