Well, how about using a slide switch? Just connect a piece of wire to the plastic slide tab (usually drilling through it works best...) and, with appropriate bends, run it in/under/through/around things to the turnout. I've done this with my Bend Track module and been very happy with the results.
You can make a small lineside building to cover the black slide if it bothers you, and move the building back and forth to operate the turnout. I use Atlas code 55 track and turnouts, and by using a DPDT slide switch I can not only change polarity on my turnout frogs, but I've also scratchbuilt some dwarf signals to indicate turnout position (using surface mount LEDs).
Mounting the throws was easy... once I got the slide switch wired electrically, I cut a hole in the foam that was a "press fit" for the switch, then threaded the wires through and out the bottom. A bit of tape there to seal the bottom of the hole, then fill the hole about 3/4 with hot glue and press the slide switch in place. Fast and easy... and it insulates your wiring, too!
