debounce problem

dhenry:

I doubt worrying about contact degradation is worthwhile at this point.

If you think this discussion is about contact degradation, you haven't understood this discussion.

Well, you are the one that quoted MarkT's comment about possible contact degradation and stated it was the most insightful comment in the thread (see below).

dhenry:

The existing 10uF is being shorted into the switch each time it closes creating a tiny spark, which may eventually erode the contacts if the switch is small.

The most insightful comment in this whole thread.

MarkT is absolutely right here.

If you expect people that can't/won't do your experiment to know, rather than guess, about what you are refering to maybe you should tell them. Cryptic advice is of little use to anyone.
