Ok, OK, OK; Sanity check here, folks....whew! At about the 40rh iteration and people reading still don't have a good overview, of problem / question / goals.
Then, suddenly, oh, its for audio. FORGET THE COMPLEX ELECTRONICS, for one second: (unless you wish to learn, that's ok). Bouncing from one partially stated 'function', to another, incomplete and complex solution.

Is that switch-set with one down, and stays like that, until some other push button is pressed ?
I mean, like your '67 Chevy vintage car radio has ?

Sounds like you want a multiple selector, for audio, but then you imply audio / constant current, using non-existing symbol 'CC'.
I know of a rotary, 6 position switch, that likely can handle 750 mA, and even better has TWO decks, so has DP6T, That's double pole, six throw. And has nice 'chicken head' style knob.
