Agree how do you hook up a switch to a light are not
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. Turn off the circuit breaker supplying power to the switch circuit that you will be working on.
