Most of us use light switches every day to set or adjust the level of lighting we need. Ourrecessed fixtures, pendant lights, chandeliers and wall sconces are usually turned off and on by flipping a switch that’s on a wall somewhere. Most of the time we don’t give the switch itself much thought. But the kind of wall switch we use, and knowing the way each kind works and needs to be connected, can be essential if we want to make some changes or improvements to the way our lighting works.
There are really only three kinds of wall switches that are used to control light fixtures: An On/Off switch, a 3-way switch and a 4-way switch. Choosing which one you need depends on how you want to be able to control your lights.
