How best to wire them?
They're not polarized, I know that.
Yet, should i hook the same side of one to the same side of the next and on and on like that?
I'm saying doe it matter at all that I use one side or the other for ground on each one?
Or, can i literally pick EITHER side of EACH "2 solder-point" SPST momentary to connect up the ground
and wire 'em all together any old way.
What's best practices?
[Stranded VS Solid core wire]
I remember a long time ago using tiny stranded wires to do a SIMM module MOD in a computer --
Wasting 100's of hours 'till i found out solid wire was the only way to stop some kind of internal
electronic reflection that caused crashes.
Of course the arduino is slower though will I need a bit worse/higher? debounce setting
IF I use stranded wire to wire up all the bunch of BIG SPST momentaries?
HUGE thanks for your time - it's been So awesome being here!
Who knows, we don't know what you are trying to do with them. Are
they to be readable independently - that suggests a multplexed array and
that needs a diode per switch if you want to be able to sense several on at
once correctly.

That's high speed logic, you need to arrange the conductors over a groundplane,
think that's what you are refering to. High speed here means like 333MHz.
For switches pushed by a human, the kind of speeds involved are a few Hz, 8 orders
of magnitude slower, not a worry. Wet string would work!
In fact you need to debounce the signals (usually in software) specifically to avoid
seeing events on the timescale of a few ms or less.
ok, so no multplexed array - figure 8 SPST's -- EACH hooked up to one digital pin.
Each SPST has only two poles to solder to of course.
So, is there anything i need to know about how to wire each side of each SPST together?
I don't believe there's any? difference between the two solder points on each SPST?
I mean, one side isn't ground and the other 'not' ground. ?
Plus, should i just sold a bit of wire between the whole eight of them going from identical side to identical side --
resulting in me holding one ground wire to solder to ground at the end.
Then use one wire for each SPST for the other as yet UNsoldered side, and hook them to each digital pin needed?
yeah, I know I may sound inept entirely though I've found little things like assuming I can wire
all the grounds together any old way -- might cause a problem resulting in UN-soldering. keen to avoid that
Let's say each switch has an A terminal and a B terminal.
If you connect all of the A terminals together with a wire from the A terminal string going to an Input pin and connect all of the B terminals together with a wire going to Gnd - then the Input pin will be Low whenever any switch is Closed.
If you connect the A terminal of Switch 1 to an Input pin and its B terminal to Switch 2's A terminal, Switch 2's B terminal to Switch 3's A terminal, (and so on)... with Switch 8's B terminal to Gnd - then the Input pin will be High till all of the switches are Closed.
Yes - that's basic and yet nice twist in your explanation part 2 particularly.
My question IS:
for an SPST are the 2 poles ideantical ? Can I use either side designated as ground?
and if so, can I willy-nilly choose one side then the other when stringing them together in a loop, connecting the last one to ground? And then each of the unused solder points on each of the SPST's connect each one to it's required digital pin.

Which pole/terminal is irrelevant, it doesn't really matter. It might be a little easier on you to be consistent in application, pre-designating, for your own purposes.
Yes, for the sake of less confusion that I'm capable of, to get the right answer(s) I asked about 'willy-nilly' wiring and the likes.
very into best practices and your comments has been most helpful here.
