Replacing a standard, single pole, wall light switch is an easy DIY project that only requires a few tools and a little know how. Here how to go about it.
How Switches Work
Switches work by controlling the flow of electrical current in the hot wire, with power coming in through the wire attached to the bottom of the switch and going out to a light or other electrical device through the wire attached to the top.
Hot wires in a house are usually color coded black or red, with neutral wires white, and ground wires bare or green; but under certain conditions, the hot wire to a switch may be white as well. If the hot wire is white, it should be wrapped with black electrical tape to indicate that it’s functioning as a hot wire.
