Review on Rule 37A SuperSwitch Switch Moisture by Dave Albright

I bought this switch to replace an old mercury switch I had that had lasted countless years. Based on my online data, this model has received better ratings than the standard rule model. I don't know what's "great" about this switch, but so far so good after a month in the hold of my sailboat. The time will show. If I get a few years I'll have to upgrade it to 5 stars. If not, I'll have to downgrade it and look for an alternative. Unfortunately, there seem to be several viable alternatives to these mercury-free roller switches.
