Really a good question. My switch disconnects the starter cable. I've read about "safety issues" when breaking the "hot" cable, but like you I don't really understand why. My rationale for why it is a safety issue when breaking the negative "hot" cable is that if the switch should short out internally, there could be a lot of fireworks with no immediate way to shut the power off. Using an in-line circuit breaker on the negative cable between the battery and the switch could solve this problem, but I haven't seen any cables like this advertised for an A.
