Once you have found where on the cord you want to put the switch box, mark it with a piece of tape. I ended up making the first 5ft or so of the extension cord the 'plug' side, and only about 1.5ft the 'outlet' side. You'll also want to have some extra length from the plug to the switchbox, so you can reposition the switchbox to be near your foot as you work. Wiring the box itself should use about 8' of the total length of the extension cord. Keep in mind that the cord needs to be long enough to reach from whatever outlet you are using, down to the floor beneath your feet, and over to a place that the tool you are plugging into it can reach the outlet. The first thing you need to do is find out how long of an extension cord you are going to need.

The washer needs to have a center hole just large enough for the switch mounting threads to fit through, and have a large enough diameter to completely cover the hole in the 4' square cover top plate. Your washer sizing will need to correspond to what size the mounting hole for the switch you are using is. It's a good switch to use, though- not too expensive, it's rated for so it's good for most small tools, and it is designed to be hit with a foot so the switch top is metal and quite sturdy. Almost any pushbutton switch can be used, I just happened to have this switch ordered from DigiKey for another project, and decided to use it. I had to buy an extension cord but most people have one or two kicking around in a drawer somewhere- many people will also have the washers, and possibly even the electrical box gathering dust in some corner.
