What is the best way to toggle between two capacitor values, when (the larger) one is an electrolytic and the other is not?
Was thinking about a plain 'ol DPDT with the larger cap soldered across the center lugs, and the other cap across one set of the outer lugs. (C1 and C1+C2 options)
My concern with this is that they might be out of balance, as one of the caps is polarized and the other is not.
That led me to the idea of switching C2 in series with C1 (adjusting the value of C2 to get the desired overall value when engaged). I'm trying to keep the switching effective, while avoiding popping.
Which of these (or others) would be the best practice?
