Nice switch
I was getting interference on my humminbird solix from my trolling motor through my on board charger, this switch allowed me to isolate the charging connections to prevent cross talk.

Nice enough switch, but...
The switch is nice enough, but it smells to high heaven. Requires some baking soda. Sun and air won't do it. The spacing is really tight and 12AWG is a pain. Once you get pasted that it works good.

Well made
I installed this switch on my pool pump system. It’s fairly easy to install, and feels heavy duty, and most importantly, works well. Delivery was fast, just a couple of days.
