Installing a three-way switch is a common electrical task that can be completed in a few steps. A three-way switch is a type of electrical switch that allows you to control a light from two different locations. This is useful for controlling lights in hallways, stairwells, and other areas where you need to be able to turn the light on or off from multiple locations.
Three-way switches are more complex than single-pole switches, but they are not difficult to install if you have some basic electrical experience. Before you begin, make sure that you have all of the necessary tools and materials. You will need a three-way switch, a screwdriver, a wire stripper, and electrical tape.
