When the light switch is needing to be changed out or replaced our first thought is to call an electrician who will be able to come and do it for us. This is a great way to handle it – but expect to pay around $40 or more for them to come into your place and spend ten minutes to put in something you are able to simply do yourself.
Before you begin turn the electrical current to the switch off. You will be able to do this at the power circuit or the fuse box. When that is done you will need to take off the cover plate that is over the existing switch.
Now take off the screws that are securing the light switch into the wall box. Gently take out the switch by pulling on the tabs that are situated on the top and bottom of it Wire Pull Tester. Use a voltage tester and test both of the lines connected to the unit. This will tell you whether or not you were successful at turning off the power.
Untighten the screw on both sides of the wire. Twist it up and away from the unit and loose the bottom screw. Bend it downwards from the unit and loosen the screw that is securing it to the ground wire. Now throw away the old switch.
Undo each of the screws that are on the new unit and wrap the ground wire round the screw and secure it. If the wires are in the right condition than you will have the ability to twine them around the bottom wire and screw and tighten them.
Now twine electrical tape around the brand new light switch. Be sure that the terminals have been covered so that the ground wires do not touch the them. Carefully push the wires into the wall box and secure the mounting screws. Screw the cover plate in and turn the electricity back on.
