Need Help With DIY Switch Box

[WhenKittensATK]

I recently purchased a Bottlehead Crack, however I don’t plan to use my speakers and all of my headphones with it. So, I’m thinking I’ll probably need to build a DIY Switch Box to consolidate all the inputs and outputs to avoid cable swapping. I have no experience with designing or building electronics, so I’ll need your help with that.
 
I drew a diagram of what I’m hoping to get out of the build. I hope it makes sense. I basically have two inputs, Audio-gd NFB 15.32 DAC and Bottlehead Crack. I want to be able to toggle between the NFB 15.32 and Crack, like an A/B switch. I also want to be able toggle output to my speakers (only turned on, when in use) and 4 headphones.
 
Sounds simple, right? I honestly wouldn't know. So this where I need your help:
 

1. Do I just buy single solid/stranded copper cables for the internal wiring? If so, what kind?
2. Is there something I need to solder the 3 way splitter or can I just solder 3 ends of the wires together?
3. What would I need to wire the 2 input / 1 output toggle switch (Probably will mount it to the front of the case)?
4. Any suggestions of parts for the RCA, headphone jacks, and rotary switch?

So you want 2 options:
 
1 to switch between your speaker amp and the headphone amp
1 to switch between all your different headphones
 
correct?

Correct.

I question whether it is worth it to spend money on a DP4T switch for the headphones, since it will be expensive. I would personally just plug and unplug the headphones honestly, that's what I do now
 
As for the switching between the headphone amp and speaker amp, you need a 3PDT switch (3 pole, double throw) since you need to switch GND, L, R (3 poles) between 2 different positions (2 throw)
 
ELMA sells a bunch of stuff like this, not sure how much it costs as I have never made one. You could probably get away with only switching the L,R, leaving ground connected, if you prefer.

If you gonna DIY modding, you just add the headphone connectors to those switches/housing.
The 3 input and 1 output are reversible as 3 output and 1 input, because its just mechanical wiring together.
