One of my brother Paul’s recent jobs was something right up my alley, and I was happy to help out. His customer wanted to add a light over the sink, which not only involved installing the light fixture itself, but required running wire to it from an existing wall switch. We then added a switch to control it by changing the single toggle switch to a double.

When we finished, we thought it might be fun to make a video on how to wire a double switch. If you are interested, click here to take a look.
