I don't think the 4-way rocker switch is the best choice.  I need the
switch to stay in position and give the end user an indication of what
 "port" they have selected.  I have seen small devices with a four
position slide switch.  I just never thought it would be as tough as
it's turning out to be to track one of these guys down.

I agree that DIP switches aren't the best fit for this application.  I
have found a rotary DIP switch that might work but it is a bit pricey
(for me) at $1.86 in 500 piece quantity.  I can buy a knob with a
pointer so the user can see what is currently selected.

Thanks,

Richard Cooke
