Title: Toggle switches for toggling?
Post by: Lubdar on June 01, 2016, 12:22:16 PM
This is kind of general, but I'm planning on switching the input capacitor into a circuit between a smaller (0.047uF) and larger (10uF) value. Is there any reason why a DPDT would be preferred over an SPDT?

You only need a single pole, single throw.

Thanks Jon,
If I understand correctly, running in parallel I can toggle the 10uf with the spst to increase the capacitor from 0.047uf to 10.047uf.

Yup.

Ahh good to know SPST is more efficient for this situation.

Follow-up question: in the Pig Butt schematic there is a DPDT used to toggle between the tone stack and tone-bypass; would a SPDT work there?

In the Pig Butt, the ENTIRE tone stack is removed. It's just like bypassing a whole effect. You have an input, an output, a circuit input, and a circuit output, with two common points and two different places for those common points to connect. Add all that up and you get two poles and two throws.

ahhh gotcha!
