Larry -
I don't know if I've talked to you about this yet, but I modified my switches
to work on air power. This involves drilling the switch apart and gluing it
back together, but it _is_ an all-LEGO solution, and relatively cheap, too.

I used to try to run this with a compressor, but I've found it works much
better to just use the standard thumb-operated yellow pump. I currently have
two of my switches set up for air, each with about five feet of hose, and three
or four pumps is plenty enough to throw the switch.
Later,
Matt
