To install an electric switch in the home, turn off the electrical current to the switch, remove the old switch from the wall, remove the old wires from the switch, attach the new switch to the wires and reinstall in the wall. If a person has not replaced an electric switch before it is best to enlist the help of an electrician.
Installing an electric switch is an easy project that should take less than half an hour. The only supplies needed are a new light switch, screwdriver, pliers, a multi-tool and electric tape.
- Turn off the electrical current
- Remove the old switch
- Install the new switch
Before attempting to remove the old light switch, turn off the circuit at the breaker box. Be sure there is no current to the switch before attempting to work on the switch.
Use the screwdriver to remove the switch plate from the wall and set it aside. Unscrew the old switch from the wall and pull it out. Note the layout of the wires holding the switch in place. There should be two black terminal wires and one green grounding wire. Loosen the screws holding the wires in place and remove them from the old switch.
If the ends of the wires have frayed, clip them and leave about a 1/2 inch of wire exposed. Bend the wires into a hook and attach to the proper terminals on the switch. Place the switch back in the wall, secure with screws and replace the plate.
