Bob Cordell initiated a discussion on relays (for output/speaker connections) very recently (a week or so) so if you don't get much response here you might try that thread as it seems to be looking at most of the options and the relevant expert were involved at a fairly serious level.
You want something that won't degrade over time (oxidisation of contacts), so go for a sealed relay type or possibly glass reed relays. All these OK for headphone levels as well. Have used reed types successfully in past but prefer solid state switching for small signals.

Hi,
Look for the signal relays like the telephone company uses. They are low power and either irridium (sp?) or gold plated contacts.
Fujitsu makes some that are relatively inexpensive, small and burn peanuts for coil power. Can't think of the model # off the top of my head though.
Cheers!
