i've never seen one before, i wish i could see one in person
I'm sure you could see one at any good chandlery like Hamilton or maybe Jamestown. As you can see, you can put the switch anywhere even out of the bilge. The Jabsco Hydro-Air switch is basiclly the same thing too.
Ultra safety. I have installed many (over 20) for customers and never replaced one yet. You will buy 5 rules before you replace one of these. You will not be disappointed.
