Really Simple Audio Switch (2 Inputs, 1 Output)





Introduction: Really Simple Audio Switch (2 Inputs, 1 Output)

This is a project developed during our "Taller de Inventos" (AKA August Build Night), sponsored by Instructables and Jameco, that provided some of the components for this instructable.

It's a case that holds an audio input and two outputs, enabling you to choose the audio source for your amplifier or speakers.

Here's a video of the switch

It’s a really simple and nifty hack that we wanted to share :)


x1 DPDT Toggle Switch on-on 2 way
x3 3.5mm jack PCB stereo
x6 Cables (5cm each)
A box or container for your switch
Glue (of a powerful kind ;) )

Soldering iron
“Helping Hand” holder for soldering [Optional]
Dremel or regular drill

This part is up to your imagination. We used a small wooden box that we had lying around.

Step 1: Find a Case for Your Audio Switch

The first step of this instructable is finding a small box for repurposing as the audio switch.

Some suggestions are:
- Altoids box
- Small wooden box for jewelry
- A cassette tape box
- A metal cigarette case

Step 2: Soldering the Components

Once you’ve settled with a box or case, solder the jacks to the switch according to the diagram.

Step 3: Preparing the Case

Now you’ve got both the case and the circuit, it’s time for everything to fit in nicely together.

Drill the necessary holes on your box for the jacks and the toggle switch. Put every component on its place and, if necessary, glue them to the case.

This isn’t a rigid instructable, so make sure you design your switch as imaginatively as possible :)

Questions & Answers


Made it! For mine tho, instead of going to an output, it goes into another switch to control 2 outputs!

Just made one! Thanks for the instructable. I used an on/off/on switch so I've got an off too!

Good idea :)

It was a fun build! This was my first time doing this and from what i can tell, it came out perfect!!
