This is interesting discussion. As an electrical worker, I've always been taught to never interrupt a ground cuircuit. So I wired my cutoff switch to the positive side with that frame of mind. Works fine for what I use it for.
But, have you ever noticed that any automotive book or instruction manual tells you to disconnect the negative battery terminal before you do any work that involves the electrical system? Hmmm..... more food for thought.
