When wiring up a new switch its the ground you interrupt with the switch right?

battery-->fuse---+on_device

-on_device-->switch-->ground

That is one way. But most wire it.
Battery-->Fuse-->Switch--+on_device-->Ground

You switch power for safety purposes. Switching ground leaves an "hot" open circuit that can easily short to ground and come on w/o notice.

Dingbat is correct. Everything equal, you never switch the ground leg. Normally, when you switch something off, you want power removed from it.

The vast majority of the time a switch is placed in the positive wire. This is considered the "normal" way of doing it.

Many years ago there was nothing strange with switching the negative as it use to reduce arc burn on the contacts. On todays wiring switching the positive is the normal practice.
