I agree with Carl, a foot switch can be a option for a Unimat.
I've been using momentary foot switches almost exclusively on my Unimats and several other tools that benefit from "hands-off" power control. I wouldn't suggest anything but "momentary" operation as these supply power only when depressed (like the accelerator pedal in your car). I think a "latching" or on/off footswitch could be dangerous in some situations.?
I haven't upgraded to DC motors yet, but when I do, there will be a foot control option built into the power distribution.?
I have a couple TEMCo branded switches pictured below which have been working flawlessly for hundreds of hours. The $12 Wen in the link looks similar and a good value.?
