How do you replace a basic light switch that is mounted on the wall?

Answer 1

FIRST OF ALL YOU HAVE TO FIND OUT WHICH WIRE IS YOUR INCOMING POWER AND WHICH ONE GOES TO DEVICE. MOST ANYKIND OF ELECTRICAL VOLTAGE TESTER WILL WORK THAT GOES UP AND ABOVE WHAT YOU ARE TRYING TO TEST. GENERALLY SPEAKING THERE WILL BE A BLACK AND WHITE AND POSSIBLY A GROUND IN ANY OF THE CABLES COMING IN AS LONG AS ITS NOT A FOUR WAY OR THREE WAY.THE BLACK WIRE IS SUPPOSED TO BE THE HOT WIRE COMING IN AND YOUR WHITE IS THE NEUTRAL. THE BLACK WIRES ARE THE ONES THAT ARE SWITCHED AND ARE ATTACHED TO SWITCH ON THE SIDE . ON A SINGLE POLE IT DOESNT MATTER WHICH ONE GOES ON THE BOTTOM OT THE TOP THE SWITCH ,IT WILL STILL BREAK THE FLOW OF ELECTRICITY . THE WHITE WIRES ARE TIED TOGETHER AND PLACED AS FAR FROM ANY OF THE HOT FEEDS AS POSSIBLE FROM THE BLACK SWITCH LEGS. IF YOU HAVE THE GROUND WIRES , TWIST TIGHT TOGETHER LEAVE ONE OF THE WIRES LONGER AFTER TWISTING TO ATTACH TO THE GREEN SCREW ON OUTLET FOR GROUNDING IF NEW WIRE. OLDER HOUSES ( 50 YEARS OR SO DIDNT HAVE GROUND WIRES . ATTACH TO BOX AND MAKE SURE YOU HAVE VOLTAGE TO THE SWITCH BEFORE ATTACHING THE COVER.
