I'll second the motion regarding silicone (dielectric) grease. *I've
started using it on just about everything, even dipping wire ends in
it before crimping them. * You can buy a good sized tube of it at NAPA
for about $3 which makes it a real bargain.

Sounds like your switch may have to be labeled "under sail" and "under
power!"

The last of my old sailboats had 3 switches, one for the masthead
tri-color, the original for the deck mounted lights, and the third was
for the mast mounted steaming light.

I know others disagree with me but I solder and then heat shrink
connections that have corrosion potential. *But then the wire needs to
be well secured. *The solder makes that part of the wire rigid and if
it flexes somewhere nearby it may eventually break at the end of the
solder joint.

I found out years ago, that solderless connectors always work best
with a drop of solder on them.
