Many thanks David!  If I know Digikey, they want $3 for the part and $20 to
ship it, but will have to check.  I think I will go with eBay... thanks for
the correction about the type of switch as well.  It makes sense that it's a
single pole,  as it only has a single power source. The double throw part I
assume lights the yellow and red LEDs.

As to the other sender units mentioned, if one uses a different receiver
gauge, it's possible.  I just don't see any subminiature gauges that might
look good mounted in the stove panel. I spoke with West Marine about this
earlier.

I do agree that the one that uses the electrodes is not very elegant, but it
would work too.

I will break out the solder gun and get busy! Wish me luck.
