Robusto e affidabile
Provato con corrente di 100A e non diventa neanche tiepido. E' tutta un'altra cosa dagli stacca batteria cinesi. Anche le dimensioni sono monto abbondanti. Ottimo

High quality disconnect
Solid item, does as expected. The product seems top quality. Used as a battery disconnect for a camper, I used it in a modular battery box and it's sits super tight using a 3 5/8 hole saw. I used out door sealant to waterproof around the hole.

Buy this, not the cheap Chinese switches. Safety is worth the price.
Bought this for our self built camper to replace one of the cheap power switches that are all too common on Amazon. The old one was getting extremely hot even though it was operating well below its rates current, hot enough that what alerted us to it was the smell, it had only been installed for a couple of days. You get what you pay for, the quality of this switch is great, handles higher currents than the last one without even getting warm. I'm confident this one is actually rated for the current it states. Easy to install, works great. The old one was dangerous. Don't buy the the cheap Chinese ones, they're dangerous & a false economy. Spend the money, buy one of these. It's not worth the risk of an electrical fire. We've been living in our van full time for a year & a half & we've never had an issue with this switch with it regularly handling 165A when running an air fryer on our 12V leisure battery.
