Row of switches that will only allow 1 to be on at a time

As you can see by the title, I'm looking for a way to have a row of switches where only 1 can be on at a time.

They'll need to be 3PDT and hold at least 4. I've had a look but it's SO hard to find.

More info:

Essentially, what needs to happen is when you push one down and then push another one down, the previous switch pops back up.

If this can't be found mechanically, is there a way to simulate this with various components and maybe momentary switches?
This is a strictly analogue project as it's for a strictly analogue friend. ^_^

They are called interlocking switch assembly. Quite common on push-button switch assemblies.
A diagram for an electronic version is attached


Hmm, somehow I can not add an attachment. Send me a PM and I email you the schematic. E

Thanks, I'll PM you now.

What voltage/current do the switches have to switch? Bandwidth? Any limitations on the power supply for this circuit?
