Battery cut off switch question
All along, I've been under the impression that a cut off switch should be placed close to the battery and on the positive side of the system. Is this right?

On a trailer it must be on the positive and the breakaway switch should be wired prior to the disconnect for safety. Sooner or later the trailer will be towed with the disconnect open but the breakaway will still function.
Breakaway switches can malfunction, brake wires can become shorted, keys can be accidentally pulled and there is no fuse, so do you keep a wire cutter right there to quickly disconnect before there is a fire?
Now, you are being silly. Beemerphile1 is spot on. A disconnect switch, which is the subject of this thread, does not protect from any of the things that you mention.
You did not understand, if there is a fault the disconnect switch can be used to quickly remove power. I might be silly but I do have a clue about circuits with no fuses. Wire it any way you like, I don't care.
Actually, I understand fully. If there is a fault, it is unlikely to be while you are standing there to hit the switch. There is a reason why NO manufacturer wires a breakaway switch through a disconnect switch.
