I use this foot switch to actuate a Dremmel tool. I like the fact that it's on/off (as opposed to a momentary on type switch) since I frequently run the tool for several minutes at a time. This way I don't have to keep my foot on the switch yet retain the ability to quickly step on it to turn off the power. The construction seems to be HD so I expect the switch to last forever (well at least for a long time.) It also comes with plenty of cord wire.
