Blue Sea Systems BS9003E Battery Switch Series e on/Off, Unisex-Adult, Multicolor

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.

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.

Muy practico

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

The Blue Sea Systems 9003e battery disconnect switch is very high quality with a solid feel and tough plastic housing. I ordered this switch for my electric golf cart. The voltage rating of the switch exactly matches my 48 volt system and far above the 200 amp maximum of the golf cart. I don't expect to be switching off the power while current is flowing, but good to know that the switch is capable of handling anything that the golf cart can produce. I mounted the switch from the rear with only the round face exposed for a more professional look; The minimum hole size is 3 5/8" to accept the round part of the switch; had to borrow this large size hole saw from a contractor. The studs on the back are 3/8" diameter and easy to access. The only thing that could be better is if it came with a non-metallic cover plate for the back to protect against accidental contact with the studs; This is not an issue for those who are surface mounting the switch. All golf carts should come with a maintenance switch like this. I can now be assured that there are no parasitic current draws on the battery pack when not in use. You just have to remember to turn it back on when charging or when you want to use the cart!

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.
