DIY Audio Switch

I want to be able to switch between headphones and speakers at my desk, but I also alternate between using a laptop and desktop at the desk. To make switching between all of these possible configurations easy, I made a device using 3.5mm audio jacks and toggle switches that is housed in a 3D printed enclosure.

Here is a link to a Google drive folder that contains the .STL files for this project, and a small parts list:

You could use TRRS jacks (4 pole), that way it is also compatible with headsets with microphone, although you also have to find switches with extra pole.

Looks like only 1,490 viewers of same ideas are watching this... Unique thinkers

[@AwesomeRedKite]

you got a wiring diagram?

[@rom260]

If somebody doesn’t find themselves competent to do DIY, there is an audioswitch headphone stand that does the switching between various audio outputs automatically.

Great project

Good video, i enjoyed it. this may simplify my dual pc setup :) ... and now the (hopefully constructive criticism). dark devices on dark backgrounds = not good (wtf am i looking at).
i don't know anything about you, this is aimed at helpful advice. hope it came across this way. Tinkering is the best, it's always fun making something custom, don't stop :)

Great diy project! It has me thinking tho..
Say I have 2 music sampler boxes both with inputs and outputs for each where music is flowing into box 1 while box 1's output would route to box 2's input, so 4 inputs and 4 outputs total. Would it be possible to make something similar if I wanted to reroute without replugging cables?
Visual example of what I'm looking for: audio out from source -> sampler 1 input-sampler 1 output-> sampler 2 input-sampler 2 output -> interface, flip a switch, and now audio's rerouted to audio source -> sampler 2 input-sampler 2 output -> sampler 1 input-sampler 1 output -> interface

Hello, is there a way to have only one audio input?

[@shdoborn]

THANKS FOR THE VID!!!
can you post a parts list by any chance fam? also, a STL file for the 3d print would be amazing. my use case is 1 input 2 output, ill have to figure out the wiring for that change though unless you know.

[@twilighttinkerer6840]

Easily done playa. This Google Drive link has the STL files and a parts list as a text file.

For only 1 input 2 output, you basically just don't need a 2nd switch. Connect the wires from the two audio output jacks to a switch like in this video, then you can connect the middle row of the switch directly to the audio input jack leads.

I was thinking about doing this too since I have a pc laptop and Mac mini, with bookshelf speakers and a gaming headset. Luckily my monitor has a 3.5 mm aux jack so I’ve been using that for outputting the audio from the computers to the speakers (audio via hdmi and DisplayPort to the monitor). Because I have a gaming headset with a mic, I need to use 3 trrs jacks and a single 4pdt switch so it’d be a little cheaper than your setup. The sescom one is overpriced.

How does the data (L&R) from one input go to the chosen output?

[@itsasinine3337]

analog, purely mechanical

[@E_SwasK]

Can you please make one with 4 devices , 4 Pcs ' I can't understand how to construct the circuit

[@sytiravajous]

Look up how DPDT switches work, that should clarify some things out.
For your project you'd need dual way rotary switches with 4 positions. They work the same way as DPDT, but has as many more pins as there are positions.

[@E_SwasK]

@@sytiravajous understood, maybe I need to watch a few more videos to understand the circuit
