Questions about electron flow regarding switching components in effects circuits

[tweaked]

Example 1 (Opamp Stacking) - How is it possible that by switching the power to each individual opamp, you are also eliminating the electron flow to the ones that are not engaged? It seems to me, if there is an input of electrons to an opamp, and the electrons flow through it to the output, and all the other opamps operate the same way, then by stacking the opamps and connecting power in/out to only one of them, you are effectively sending power to all of them at the same time (since the other pins are connected.) It seems to me that you'd have to not have any of the pins touching on any of the opamps in order to truly isolate each opamp from the other. Can someone explain this in words or better yet a diagram?

Example 2 (Switching other components) - Take the upper left portion of the following diagram for example (from generalguitargadgets wah mod)... How is it possible that only one cap at a time is affecting the circuit? I would think that by selecting one cap, you send electrons through that cap, but then since the other end of all the caps are effectively connected, wouldn't some of the electrons bleed in to the other caps? It seems to me the only way to avoid that would be by isolating the in and out of each cap when you switch. Is it because they are directional and therefore don't let any electrons back through them? Also... 1. is the same true for other components such as diodes and resistors (does directionality have anything to do w/ it? etc...) and 2. What would the diagram look like if using a 2P6T rotary switch?

Could you shrink your picture, it is so big that I can not read the text and since the scroll bar is off the screen I can't easily scroll to read across.

Yep. Impossible to read the text with such a large picture.

EDIT: As another poster pointed out - the schematic clearly states that it is not permitted to repost it.

Next time you have a question about a (big) picture, please just post a link to it.

Read the sentence at the bottom of the schematic.

There is no actual electron flow through capacitors.
A capacitor is 2 conductors seperated by an isolater, theres no way an electron can jump from one side to the other (well in a perfect capacitor). They do however let through AC signals because the voltage is constantly changing. Thats why capacitors are used to block out DC bias voltage while leaving the main AC signal there.
well, not the best explanation as I've allready forgotten most of what we learnt about capacitors in physics  if you an apply a voltage on one side of a capacitor it generates and electric field that brings in/drives away electrons on the other side


also, for your first question, with opamp stacking don't you end up switching the inputs and output in/out, leaving the power constantly connected? i don't know since I've never really tried it

Trying to edit the post but no edit button...? Mod?

Seljer to the rescue, again :-) Thanks man! What about diodes/resistors? How would you hook those up to a rotary?
