I have a battery eliminator for old vacuum tube radios. It supplies 12 different voltages via a terminal strip. I'd like to connect multiple radios to it, but it can't handle the current.
So, I'd like to build a switching device that is fed by the battery eliminator and goes to a few selectable terminal strips. Then I select position 1 to power those 12 outputs, position 2 for a different 12, etc.
Short of having 12 individual spdt switch, anyone have a cheap, non-relay solution that takes 12 inputs and switches them between 2 sets of 12 outputs? Bonus if I can get more than 2 sets of outputs.

Your google-fu is weak, grasshopper.
Don't those switches switch 1 input to 12 positions? I need 12 inputs switched.
A 12 pole 2 position switch will switch 12 separate connections, but you have to look at the current capacity of the switch to make sure it will handle your application.

Are all 12 connections used at one time for each radio? How many amps is the largest load?

Input vs output does not apply to a passive electric switch. It's just making an electrical connection, like moving a wire from "A" to "B." Do wires care which end is the input or output?
Just so you know this is more of an electrical than electronics question 
It's definitely an oddball thing you're doing. Would 12 SPDT switches mechanically linked together be so bad?
