Actually, now that I look at this, I think it will only work with 
momentary pushbutton presses, as the relay windows have to be half the 
voltage used, as the voltage has to be high enough to energize both 
relays in series.

I saw this design on another site, and the caveat was listed there, so I 
think it applies here.
