Blue Sea Systems - Battery Switch ON/Off AFD

Quality switch

The switch was a breeze to install, feels very solid, and I expect it to last a long time. I'm sure this is a little over-kill for my single marine battery, but I'm willing to pay an extra twenty bucks for peace of mind. This switch has a very high threshold for the load of amps that occur upon starting the engine, and it's size and weight imply that I won't be replacing it any time soon. The ability to flush-mount it worked great and keeps it looking professional. Regarding my specific setup: I have a standard marine battery running to a 120hp Yamaha outboard. For the last couple seasons I have had an issue with the battery dying if I didn't use the boat for several weeks. Physically disconnecting the battery terminals after using the boat solved the problem, but it wasn't the most user-friendly solution for the rest of the family. The issue suggests a larger trickle from the battery than there should be, but it's not worth my time or money to figure out what device is pulling current even when the key is off. So the solution was to get a simple switch that does the same thing as physically disconnecting from the terminals. It's worked great so far; no battery drain after leaving the boat for a month. Originally I intended to mount it below the dashboard, but I ended up taking more simple route and mounted it closer to the battery in one of the compartments under a back seat. I used a 3 5/8" hole saw to cut through the plastic wall of the seat, about halfway up from the floor. Then I pushed the switch into the hole, marked the four locations of the bolts, drilled four small holes, and mounted the switch with four nuts and bolts. NOTE, I needed the following extra materials to install the switch: 1. 3 5/8" hole saw (not needed unless flush-mounting, and you could use a different tool too) 2. Four bolts and nuts (at least 3.5" in length, I forget the diameter) 3. Wire and crimp-connectors to extend the wire from the battery to where I mounted the switch, remember that you only need to extend the positive (+) cable to the switch)

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

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.

Well made great product
