The terminal numbers are insignificant. You can wire it either way.

Multi-voltage systems aboard aircraft are difficult to craft for reliability and cost of ownership. The only successful airplane I've touched with a multi-voltage system had TWO independent alternator-battery systems. This was a research Bonanza wherein we drove a second alternator from the pad where an air conditioning compressor would mount. Suggest you go all 24 volt. The 12v accessories you cited are probably available in 24 volt.

Any thoughts? Would the lead between battery(+) and the switch be as short as if it were between battery(+) and a contactor?
