Touch toggles from Berritt Hills Shops http://www.berretthillshop.com/
Well, yes, they are the cat's meow. I use them on the newer sections of the layout and might yet upgrade the older SPST panels I installed before I went DCC. A simple touch will reverse the polarity and change the integral LED color.
Green = NORMAL, Red = REVERSE. Not cheap, but clean.
