I installed two deck
switches, I believe Lewmar, and have decided to replace them with Maxwell
. One of the covers broke off within a few weeks. Quite flimsy. Then one switch stopped working so I opened it up to discover a bare copper switch plate that was corroded. Interestingly the other switch had a plate that was tinned. The Maxwell foot switches have what appear to be stronger cover plates. They are actually designed to work without covers, that is the rubber cover is UV resistant, so they should last a long time with covers. The switches themselves are designed to handle high currents so should not be bothered by the low currents controlling my up/down control box, also a Maxwell. Time will tell.
