Noob question - take a component out of circuit with switch

So if you wanted a toggle type switch to add or remove a component from a circuit what would it look like?

Depends on the exact component, say if it were a resistor, capacitor or anything else with two leads, you'd take two leads where the component was supposed to be, put them in the middle two lugs of a DPDT switch then put the component on one side each lead of the component going into one lug, and the remaining lugs should be just linked together. Sorry if that wasn't that clear im terrible at explaining stuff with words, hope it helped though!

Are you asking what the switch looks like?

No, I was just asking how you would set up the components. I think
fuzz/volume-full answered the question. I'll need to look at the components themselves to make sure I understand how it works. By the way, thanks for getting me those parts so fast. Now I'm just waiting on some pots and stuff from Small Bear.

It might, if you wanted to pull the cap out and replace it with a jumper. If you were pulling a cap that is grounded, you would not want to have a jumper. Instead, just leave the other lugs open.

Thought I had it. Now I'm confused again.
Lets say using the Silver Crank as an example, if I wanted to switch between the second transistor and another capacitor, would that look like this:

Forgive the awful drawing.

That should work, assuming the transistor is only using two leads. I know some of Devi's circuits do that.
but yes, generally if you want to swap components, that's how you do it. You originally asked about how to "take a component out of a circuit" which is not the same as swapping.

This was the only example I could think of to try to get at the idea with a real thing. From the circuit layout in the other thread it looks like it's using three leads but according to chutneyfarmer you can replace the transistor with another capacitor to make the Silver Crank a Dark Boost. So I was trying to draw that out while implementing a switch.

I'm pretty sure you can just pull two of the transistor leads out and the third will then become useless. So it should work.

Ok. Thank you so much for helping me get it. Just needed to use a real thing as an example to understand how it works in application.
