Is the little magnet (about the size of a $15 stack of dollar coins
with a hole in it) supposed to float by itself (maybe it's just
waterlogged)? Or is there supposed to be a foam ring of some kind
that goes around the magnet and helps it float?

Thanks. This will be a breeze to fix. I can get reed switches
anywhere here in silly-con valley, and soldering is preferred to $$
replacements.

Just need to figure out the float thing...
