A while back I posted a comment about how I set up the electrical connection to my router so as to be able to plug-in a shorted HFT Foot- actuated switch and control the router with it.
At the time, a couple of folks commented to the effect of "Whatever for?"
Well, the latest project requires routing finish edges on sixty or so decorative pickets for the new deck. We have five pattern pieces the wife uses to rough cut the pickets on the BS and I, in turn, use the router table to finish off the edges with a triple-fluted pattern bit.
Well, if I ever needed an excuse to build it or a justification for doing so, this project was it. Pick up a piece, drop it on the table, step on the switch and rout right away. It works perfectly.
You put a three-way switch in series with an outlet and the router. You plug the HFT FS into the outlet and a shorted plug into the HFT FS outlet (where they expect you'll plug in the tool you want to control). Then, when the three-way switch is thrown to "include" the outlet, the foot switch controls the power to the router (tool). (When it is thrown in the other direction, power is sent directly to the router (tool).
If you want to use the FS "normally," simply replace the shorting plug with the tool to be controlled.
BTW, the reason for doing it this way is to reduce the clutter that directly connecting the router to the foot switch entails (extra electrical cable) as well as the ability to toss the FS in the drawer when not in use and have a functional router table without plugging or unplugging anything - just flip the switch and it's on.
