Poor quality
I bought and installed this unit in May and it failed during my vacation in August. Not very good quality.

Item not as described.
I got this to replace a switch on my Onan generator on my boat. The price was good and shipping was fast. Buyer beware, this item has screw terminals, it is not a switch with spade terminals.

Corrosion problem
Part corroded on boat Generator and leaked after less than 2 years. Not OEM worthy

I bought this switch for my Onan generator. It has screw lugs which I was able to adapt to spade connections. The biggest problem I found was the sensing orfice is much smaller than the original and a small amount of debris plugged the orfice after 30 minutes running time thus shutting down the generator. I'm going back to the original switch.
