How to Wire a Light Switch - Very Easy - Lighting Tutor
I have a video showing how to connect a recessed light pot light to a switch but usually most people want more than one light on a switch. So this article will explain the easiest way to connect multiple light fixtures to one switch. But you may want to watch the video as well. TIP: Remember always shut off the power at the electrical panel before starting any electrical work. Basically the simplest way to have multiple lights on one switch is to run a power supply wire to the switch first. This would be a two wire cable black, white, ground take the black wire and connect it to one screw on the switch and connect the ground wire to a screw inside the electrical switch box mounted to the wall.
Knowing how to wire a light that is controlled by two switches as opposed to one is a helpful skill. It is a little more involved than simply wiring a switch at the end or in the middle of a circuit, mainly because there are more wires and connections involved. If at any time during the process you feel unsure about the steps or worry you might be doing something wrong, you should stop and call an electrician.
There are certain spaces within a house that that are wired with a double switch light. For example, it may be more convenient if a large and open plan living room had a double switch light installed near the door. Or if a double bay garage had a double switch light installed at the entrance of the garage. You can either replace a single switch light with a double one, or install a new switch altogether.
