It had not occurred to me that electronic switches might do the job. I
don't know if isolation will be an issue, but contact

Don,
It is my understanding that physical switch contacts are
cleaned with current - and use.
It is probably ok at the lower signal levels since from
time to time you're running the higher levels through the
switches.
Is there someway you can switch and then verify contact?
I couldn't resist. After a whole string of I'm out of the office reply
messages on emc-pstc, what shows up in the mail queue?

the problem was a cold-solder joint.
Relays sealed in inert gas or vacuum should never fail due to corrosion,
and there's no need to limit their
