Battery Disconnect Switch Questions

I have a little different take on the device. I removed the disconnect switch from my rig and wired directly from the battery to the distribution bus. That eliminates two cable connections and the switch contact resistance. It might not sound like much but that takes a little resistance out of the circuit and makes for just a tiny bit more voltage being available. Yes I'm nitpicking but a few hundredths to a tenth of a volt can be significant when load is high or batteries become a little older. Just use a small wrench to disconnect the negative cable from the battery when you need. There will be no chance of various sensors causing a slow drain on the battery when disconnected. Just my opinion.
