Ya didn't think about the rise time requirement for the j-k.
It recommends 500ns, which means the cap needs to be ~30-50pF., because I would like to keep my 10K unchanged. I'm not adding a schmitt trigger, that would be a waste of space/money.
I think this focus over debounce is a little over exaggerated, its really a matter of application.
If it was a mechanical relay that triggered ever 2 sec on an assembly line and had to be correct 100% of the time then ya, you better get that right.
If you plan to push it only once every 1-24h to switch the incoming USB lines and it 1 in 20 times doesn't flip, your not going to be hard pressed to have to press it once more.
Is there anything aside from the debounce issue that you would notice to be logically wired wrong?
