Selector switch...selection

[ggabriele3]

For a first project I would like to replicate a design like this:

Goal: switch 1 input between 4 outputs.

For the rotary switch, is it correct that I need a 2-pole, 4-position, non-shorting switch?

And, if you can recommend one, I would a appreciate that too!

only has 3 inputs, but maybe they offer a 4 input switch.

These are cheap and cheerful and of decent quality. All have adjustable end stops so either would work OK.

Thanks!

I saw this one on their site - 6-input though: Select-4

Here's a 4 input

Those Lorlin switches are very good value for money. You could make something a lot better and cheaper than that design from Douk

if it's advertised for audio, fair to assume it's non-shorting as well?

I thought so. Smaller too...i'd probably 3D-print an enclosure (unless there would be shielding issues...maybe better shielded wires?).

You could get away with shielded wire in a plastic case. Personally I'd use metal enclosure as well

You might consider switching using miniature relays; saves on complexity of the switch and the signal is not routed as for. There is a thread about this on DIYAudio. There are also designs which can be used as a template, if Googled.
