Review: Decent switch. Average price fast delivery. - Mounting screws are small/short. The housing is 1.25" thick. Provided screws are only 1.5" .25" allows only a thread or two of engagement. The 600amp switch is pretty heavy duty. I originally used a Nilight 300amp switch which failed at 200amps maximum in a few months. I ordered the 300amp Spartan which lasted two years, but still failed at less than 200amps, so we chose a 600amp Spartan which seems to be holding up.
Review: Solid, durable and built to last. - Used this on a travel trailer and installed it right on the battery box. Was easy to wire in and seems well made and durable. Connection posts are solid. I think this will hold up to the elements and is a good protection for my trailer. I did need to buy a different set of nuts and bolts for my specific application, but that was expected.
