At least now I have an idea of what sort of activation times and switch bounce that I'm facing. I really had no clue what sort of activation delays I was facing (never got this far in a project).

Now I need to test from a secondary PCB, out using wires (max 10cm) to a 1" x 1" switch PCB, and back to the secondary PCB.

That will give me actual data using the planned hardware.
