I added a foot control to my DeWalt. It is an Olsen. To be honest, I dont rember where I got it but, I think I ordered it from "Sloans Wood Shop". They have the switch for $39.95. In fact, the more I think about it, I'm sure that is where I got it.
You might find something simular cheaper elswhere.
They are not at all hard to hook up. You just plug the foot control into the wall and then plug the saw into the switch and turn on the saw swithch and tape it in the "on" position.
If you have a light, it must be pluged in to the wall outlet seperatly.
