I'll simplify the question.
What type of switches are used in your boat? Water proof or not or dont know or dont care?
Every answer is a valuable answer as something can be learned from everything and anything.
"Water-proof" is used quite often in descriptions, when "Water-resistant" might be the better choice of terms. Unless something is totally, without a doubt, beyond description potted, i.e. totally encapsulated in water-proof potting compound (an elastomeric compound would be nice), ain't nothing totally waterproof...Carling toggles with the boots are good, but they aren't water-proof...
