Thanks ZM. Sorry if I'm being a nuisance with questions, but it's nice to have some sort of idea of how things work. You're probably right, and I should invest more time in learning things properly.

Oh Mighty,
I cannot find the post where you specified the name of connectors (or complete wire) for Source Selector...

^ I'm not sure he ever did. I used a standard 14-pin ribbon cable and connectors. You can also use breadboard jumper wires etc. Lots of good options.
Here are the links for what I used to assemble cables and the headers. You can also buy the cables pre-made.

Some questions for the BOM:
Thanks
- Offset trimmers are ok 25R instead of 22R?
- Mouser part numbers for relays and ZD1, ZD2?
Thanks
-25R ok
-400mW to 500mW plain zeners
I know that ZD usually represents 1W3 zeners, but that's my bad habit of naming them like that, simply shorting Zener Diode

I thought I had sent you a full BoM with P/Ns. I still can if it will help.Some questions for the BOM:

These are what I used for my final SE build. I built a few versions, so please be sure to check the values against your schematic. There were a few tweaks over time.
K1-K5
24 VDC Non Latching Relay
817-RY-24W-K
ZD1
27V
0.5W
771-BZX79-C27113
ZD2
8V2
0.5W

Edited for formatting - my table format clearly did not work. 😀
That relay is out of stock, Is this a valid alternative? (817-RY-24D-K)

W means - high sensitive type\
D means - Make before Break switching
so, yes, you can use these
higher current draw of coil is irrelevant

^ For your own fun... look at data sheet for the RY-series of relays. See where RY-W-K is on the sheet and note what's in the far left column of text along with the coil resistance etc. in the other columns. Look at "how far apart" the RY-D-K relays are from the original part on the sheet. Then... note if there might be any parts that may be a bit closer to what you're looking for. Then check that far left column again... and wonder...
tl;dr - It will work, but you should know what specs are critical or be able to look at the sheet and ask if "this spec'ed part is OK vs. that spec'ed part". Great way to learn.
Edited to add - Or you can just ignore me, when the Mighty one himself beats me to the answer. 😀

That seems closer: 0,5W against 0.2W of nominal power, not make before break, more current necessary for coil (too much?)
