Whats the reaction time for one of those teeny 5 volt coil relays
including a reasonable debounce period? Will 20 milliseconds get me a
solid signal, or so I need even more time by the time a contact bounce
has settled?
Yes, I'd think 20 ms should work fine for turn-on.
Possibly, due to freewheel diodes, the turn-off could be
more than 20 ms. But, you can just try it, and adjust as
needed.
