I just have "all" of my avionics on one breaker/switch, which is just the radio and transponder. That breaker gets its power from the main breaker like all of the other breakers. I can't think of a time I'd want just the radio and transponder to be on with everything else off, but if the occasion ever arose, it'd take about 3 seconds to switch everything off but them. I do turn the avionics breaker off when I start or shut the engine down, just in case of some crazy spike. I have another breaker with for "instruments", which is turn and bank, GPS, EIS, mixture meter, fuel gauge, and that sort of thing. For what it's worth...
