It will almost certainly be a rotary or slide or a ganged
push-button.  Or of course you could gang up miniature toggle
switches.  RS probably has  a three-way pushbutton speaker or antenna
switch in a 2x2x3 box with connectors (RCA or F-type) on the back.

DigiKey is an obvious source.

Here's a cheaper one, got a dp3t slide switch at 3/$1.

If the current through the switch is less than 18 ma the so-called
"dry-circuit" switch type would be preferred, although they're a good
deal more expensive.  At low currents the switching action does not
exert the cleaning effect on the contacts that it does above 18
ma.  I think you're probably ok on that but I don't know.
