DIY Audio Switch

If you have one speaker with only one input jack/or cable you can use this to have 3 inputs. You can select inputs with the knob. Device is designed to be mounted under table with 2 screws.

It has 3 inputs and 1 Output but it can be used also in reverse to have 3 outputs and 1 input.

There are multiple possible versions. I have made only 2 of them so far:

Available
Audio 1 : 3 Input and 1 Output on the back side (speaker logo)
Audio 2 : 3 Input on the back and 1 Output on the front side (headphone logo)

Possible future versions if requested
Audio 3 : 4 Input and 1 Output on the back side (speaker logo)
Audio 4 : 4 Input on the back and 1 Output on the front side (headphone logo)
Audio 5 : 4 Input on the back and 2 Output on the both sides (automatic switching to front output when headphone is used)
