I looked at

http://www.analog.com/products/selection_trees/switches/switches_audio.html

and at

http://www.semi.harris.com/data/fn/fn4/fn4153/index.htm

but didn't find much : data sheets are quite short if not 
non-existent... And nobody at Harris or N.S. answered my mails yet.

Some more clues anyone ? I'd really like to have an idea on how those
crosspoint switches work. I might want to use them for a project on
which I'm working now and which I'm planing to post sometime in the 
future...
