Bought this for my Winch on my truck as a shut off switch, haven’t wired it yet but this thing is meaty and seems well built.

Because I have several instances of leaving a GPS running, or a cabin light on, and because I sometimes do not use the truck for weeks at a time, I needed a high-amperage, well made switch, to quickly and easily disconnect the main batteries when the truck is not in use. This switch is fabulous – big, meaty, and strong. It is twice as good as I need, but looks like it will last forever. Perfect for the job.

this thing is a beast. the weight is a sign of quality here. aggressive switching action that is firm every time. if you have a high draw system and you need a disconnect, this is legit.
