There are three basic types of light switches used in the home: single-pole, 3-way, and 4-way switches. The single-pole switch is used when one or more lights are to be controlled from a single location. The 3-way switch is used in pairs when one or more lights are to be controlled from two locations. The 4-way switch is used in combinations with two 3-way switches when one or more lights are to be controlled from three or more locations. The terminology used with these switches may sound daunting but the actual wiring is straight-forward and simple.

Wall switches used to control ceiling light fixtures or other fixtures come in three types. Most common is the single-pole switch , the type used to control a light fixture from a single location. For example, a long hallway or stairway might use a pair of three-way switches at each end so that lights can be turned on when approaching one end of the hall or stairway, then shut off from the other end. When used in combination with another type of switch—the four-way switch—you can arrange switches to control light fixtures from three or more locations. The name "three-way" is at first glance a little confusing.
Often, homeowners purchase a new interior or exterior light fixture, then pay a handyman or electrician to hook it up because the wires are different colors. Most light fixtures have two electrical wires with colored insulation and a copper ground wire. An enthusiastic homeowner can save the cost of a professional by knowing which wires connect to which. With this knowledge, you or a family member can do the wiring connections for one or more lights.
