I use this to control my scroll saw. It is very convenient for frequent stops and starts doing fret work. Turning it on and off quickly became a reflex, which is very helpful when a sudden stop is needed. The directions do say the foot switch needs to be covered in plastic if it will be exposed to a lot of dust. I have a DeWalt 788 scroll saw and stand. The switch is screwed to the bottom brace. A plastic cover is taped over the switch with the tape going around the brace.
