- I understand how it works. My previous posting was a bit too brief; let
- me explain a bit more.
-
- I think I saw the idea in FWW, though it could have been elsewhere. You
- hang a board (say, 8x8, or whatever fits) in front of the magnetic switch,
- with a cut-out in front of the ``ON'' button. To turn the saw on, you
- stick your finger through the hole, to reach the button. But to turn it
- off, just bang *anywhere* on the board. The point is that turning off
- the saw becomes a simple operation -- there's a large surface to aim for,
- and a very non-critical direction vector. I don't care where a toggle
- switch is; it's a small target, and you have to press it in just the right
- direction.
