Does what a cutoff switch should do. Robust enough for big loads or light loads. Piece of mind.
Pretty robust/chunky heavy metal here folks. It will definitely handle some current, and should last quite a good long while. There's not much to go wrong. The coating on the metal appears good quality, not chintzy at all. Large bolts/studs, you're medium eye connectors might not be big enough, but always good to be overkill on gage, right!? So many ways to use this, but as a general rule, try to place as close to your battery source as possible--this just helps to ensure you have no other bleeds/consumers of your battery, and that you get them all, 100% of the time. If you relocate the switch further away, you can be successful, but trust me, there'll come a day when it's just too convenient to wire a new thing directly to the battery and bypass the switch--so just save yourself that future dilemma and make this switch the FIRST and ONLY connected device to your battery. Use a low gage jumper from the positive post to the switch, something like 8 or 10 gage for regular accessories, or maybe even lower if you're going to run a Trolling motor. Either way you wire this, you can count on it. Not much more you can ask of a cutoff, good connectivity for low and high amperage uses. Easy to use, easy on the wallet, easy to install. Great Value for it's functionality.

Works well and easy to install
A very easy install. Works as intended. Just make sure you buy a small jumper cable because it doesn’t come with one.

Overall great product
Works great! Has great instructions on how to connect everything. The switch is also easy to use. Not a fan of the base color. It’s not a gray, more like an off black.

Good switch for electronics
Bought this to turn the power off and on for my graphs. Quality product for the price and seems very durable. Good option for saving the battery from draining down and keep from disconnecting the units.

Solid hard shutoff
I bought this shutoff for my boat and it works great as a main shutoff for all of the electronics. The click moving it to on and off feels very sturdy, and it came at a competitive price. One thing to note are the terminal screws are very large so expect to get some bigger connectors, but that's to be expected with how much power can be drawn through it. Also the switch only turns 90 degrees, not a problem, but at a glance that's not obvious.

Not only allows for the primary and secondary battery to be ganged together in parallel during the use of a large inverter with the engine running, it also allows the secondary battery to start the vehicle with the primary battery disconnected. Nicely manufactured, easy to install. Comes with stainless mounting hardware.
