Re: Questions: Switch Matrices - Various Manufacturers

Not sure who is going to answer you, Jim. You're the expert !!

(only half kidding about this). But if you or somebody else has a
sec, can you tell me how these things work in general? Is the basic
premise that there are too many switches to scan (it would be
inefficient to have that many control lines) so instead there is a
circuit that routinely scans each string and pulls in a binary value
that gets decoded, or something like that?

Any doc or web page that explains this?

I can troubleshoot enough to find switches in common and eliminate
wiring when only one of a string is misbehaving but wondered how this
system works in general.
