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.

Best battery switch for your boat with big engines
Very well made and easy to fit and sturdy when in place and reassuring to use compared to the usual red key switches normally fitted

Quality Item, but expensive for what it is. Bolts require 10mm Cable Lugs for attachment.

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

As stated, you need a 3 5/8 inch hole saw to lake this a perfect flush mount. I read somewhere to "use a 3.5 inch hole saw, then use a rotary tool to finish the hole". That's pure garbage. It'll only booger up your hole. The switch itself is solid and well built. I'm using it on my overlanding solar array with two LiFePO4 230ah batteries and a 3000 watt inverter. The switch will be used to disconnect the house batteries from the alternator when I need everything my alternator can throw out when using my 12,000 lb winch.

Installé sur un voilier comme coupe circuit pour la batterie moteur. Fonctionne très bien, semble robuste. Pour le perçage il faut faire un trou de 92mm et rentrer le bouton en force (le bouton a un diamètre de 92,1mm). J'ai utilisé ce trépan : https://www.amazon.fr/gp/product/B006Z7EIWS/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1.
