Well, I can see where it would be a nice feature, to be able to control the speed with a foot pedal, but I have never seen one that does. I don't understand how it would work with a VS saw. Would you disconnect the VS control switch on the saw or turn it to full speed and hook the foot switch after it some how??
I mean, John, there is actually no need for a foot switch, there is an on and off switch on a saw also.
Anyway, unless it is specific to my saws,,, I would not think of trying it. Motors are expensive.
Dave, is you switch a "dead man' which the you have to keep you foot on to run your saw, lift you foot off and it quits? Or the toggle on and off type that step on turn it on, step on again turn it off? I would think the latter would work best for standing.
