wiring Toggle Switch DP3T On-On-On

[carboncomp]

Is it posable to wire 3 input capacitors to a On-On-On Toggle Switch rather then a 3 way rotary switch?

and if so how?

Can you use a ON-OF-ON dpdt?

If so, use your treble for the center lugs, and two larger value connected to the lugs above and below that will parallel circuit with the smaller value.  

Keep in mind The total capacitance of capacitors in series is equal to the reciprocal of the sum of the reciprocals of their individual capacitances

IF you can find an "On-On-On Toggle Switch". They are very un-common.

The electrons can't "see" the handle/knob, don't know or care how you are flipping it.

Basically you just need to use a SPST (Center off) and wire your smallest value cap to the center lug, then decide your next larger value and subtract the value of your smallest cap. Find a cap that's closest for your tastes (if you wanted a slightly larger or smaller value than standard, you are paralleling caps. The 2 combined values can give you a bit more design leway. Bonus!). Wire this to one of the outer lugs, and do the same thing for your largest value. Now, take the loose ends and they all go to one side, and you run a wire from the center lug/cap "1" back to complete the circuit.

Now you flip from smallest value in the center to a larger value on either side paralleled with that smaller value. 3 cap selector switch!
