Illogical. If it was negative ground, it wouldn't be switched negative.
Quite logical. A circuit can be switched to (negative) ground.
The switch doesn't have to be in the positive lead - it just normally is...
I believe the original poster has a negative ground system with the switches in the negative cable. Isn't this where we started?
Maybe.. I was attempting to explain why it might have been that way originally - but that does not mean it's a good idea now. The only reason people put a switch in the positive lead is to isolate power from the entire circuit when it's switched off - for safety - no other reason at all.
