I have used a foot switch often. I bought the one that Lee Valley sells which is a rubber bulb with an air hose that goes to the switch box which you plug the router into. I've found you have to get in the habit of putting the switch under your work and back a little ways so that you can't accidentally step on it but have to purposefully reach a bit to get to it. Most often I use it when I'm outside routing something long on saw horses where there is nothing handy to lay the router down on. The foot switch allows me to hang onto the router until it stops spinning so I can put it down safely. I did accidentally step on the switch a few times until I developed a better work procedure. You can get foot switches which are guarded too which that isn't as much of a problem with.One thing I was wondering, is why people couldn’t incorporate a foot switch to shut their router off and on if your free handing something.
Seems like it would help in some situations where the router doesn’t have an easily accessible switch .
An added bonus of having a foot switch is that it can be used on a drill press too.
