Installing a single-pole switch is just one in a series of tasks that make up an electrician’s work, but along with running rough wiring and installing boxes, it’s a task that anyone can do and save some money in the process. When wiring a switch, there are two scenarios: You’re connecting two feeds (one power, one to the fixture) or one feed (from the fixture to the switch). The tools you need are basic: Phillips-head and slotted-head screwdrivers, a pair of wire strippers, electrician’s tape, yellow wire nuts (for two conductors), red wire nuts (for three conductors), lineman’s pliers, and a utility knife.
