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...

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.
From RFC 1925: "(3) With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead."
