I don't have an 11/20 (yet!), but I had a look at the KY11-A manual (no print
set online, alas), and it does seem to show (pg. 19) a slide switch.

Like I said, the 11/20 switch array looks exactly the the 8/E and 8/M ones
(except for colour, of course), which seems to support that the actual switch
is a slide.

Anyone out there have an 11/20, and can give us definitive info?
