I found a YouTube video where someone made their own audio switch using an old parallel switch I love this idea to select for the sound cards as it would add a retro feel to my setup but would the selector knob switch in the box be ok to use for audio switching as the wire gauge doesn't look thick enough?

Not sure it if helps, but I use a Samson SM10 rackmount mixer for my midi rack:

I can have numerous simultaneous inputs with 1 output to my computer - works VERY well.

Thanks Hudson187 but I'm trying to keep the size down from lack of desk space and since I cant find a cheap or aesthetic to my liking switch box online I'm going to make my own from an old parallel switch box but the parts I will need some help with so first off I need a 3 pole rotary switch to select the output for which MIDI device, the one I have at the local shop is this one:

I've dabbled in electronics before and I understand the basics of what I need to do but this 3 pole switch is meant for 240 V would it be ok to run audio through it? I'm looking for good quality parts so if my link above screams low quality or if you know a better one suited to audio please say. Since this is going to be built inside a metal box with some lengths of unshielded wiring to and from the switch and 1/4 inch jack inputs plus PCB what can I do to reduce interference and or noise or would this not really be a problem but when I say "really" I'm trying to keep noise down to a maximum, I'm even going to upgrade my speakers to studio monitors but more on that later as my current studio monitors and possibly my sound card (PAS 16) has way to much noise even after running "PAS *" and reducing the treble and bass.

When making this switch is there any danger to the mixer if two MIDI modules are powered on at the same time and switching between them? I read the above 3 pole switch is "Break Before Make (BBM)" functioned so I guess it disconnects the contact before making the next contact so two MIDI modules cant be sent to the one output.

We've been discussing this very thing over here: 6 or 8 channel audio mixer

@ras2a is going for some switches from "Lynep Audio." He's yet to receive them and report back.

I'm looking at the ones pictured. These are the same as the ones LGR uses in his "MIDI Mountain" video, so should be fine.

I use a few of these minijack switches: 143169576076 on feebay.

rolls rm203. thats what you what.

Thanks again everyone but I'm not looking at using any rack type because of space and they only have a single output but if anyone's interested in a 3 box switcher this one is from Jaycar:

it might be an option for me but until I receive my parallel switch box to mod I will go for something like the one from Jaycar or this one:

I'm hoping to mod my parallel box to fit both my MIDI and PC sound card switching needs so it will have the original switch and another 3 pole switch does anyone have any input for this type of build from my last questions?
