Works very well.
Well made. I used it to disconnect a battery on a motorcycle. Can’t find a dead short.

Sturdy and great electrical contact
Studs are a little large but that is actually a good thing. Works on most battery connecting cable but I did need to drill out one of my battery cable connections. So far it seems better and more sturdy than my Marinco battery selector but need to see how it is working next year. Only draw back is that it is only for bulk heads of electrical enclosures, no screw into wall capability

Needs a lot of room to mount
Very sturdy switch, but very deep behind panel mount, restricts application

Perfect
Over years these stop working as they are out to the elements on my heavy equipment. After needing to jump them to get the equipment to work I purchased and replaced about 1/3 the price locally seems to be of good quality

Definite Upgrade
I lost the key to my camper battery disconnect. I choose this product so I wouldn't have to keep track of another key. My disconnect is on the trailer. I wanted something that was Not Plastic, that can handle possible rocks and the weather (cold/sun). If you have a similar situation this is probably what you need.

Heavy duty
Work perfectly as a battery disconnect in one of my vehicles, very heavy duty, and was able to mount it inside my cab. Recommended

場所は選ぶと思いますが、良いです
大きめですが、取り付けから1年程経過してますが、シッカリ仕事してます。 １２ｖのホイールローダーの電源管理で使ってますが、バッテリーあがりが気になっていたのですが、付けてからあがることもなくなり、節約に役立っています。 取り付ける治具が付いてきはしませんが、DIYされる方なら、ホムセンで良さそうな材料を探せるはずですｗ
