A foot switch can be a handy thing to have on hand in the workshop. I built this crude one from odds and ends long ago.
Much nicer ones are available ready-made from tool outlets, and the price is not unreasonable.
A foot switch is useful when you have a machining process lined up that requires both hands for control of it at all times. I recently had a boring job on the wood lathe like that, and introducing the foot switch to it made a somewhat dicey procedure into a relatively safe one.
