Mono stereo switch?

[Muscar]

I have a class where I need to make a mono/stereo switch that you can plug into any 3,5 mm audio plug.

What I need is a small chip with a button that can switch the audio from stereo to mono and back, like this:

My question is, where can I get such a chip, a simple ship with a stereo/mono switcher, the rest I can do myself.

Honestly.. Just take a regular cable and get a switch which suits this.
As in, when switch is on the cables go through like they normally would.
When it's off, the left and right speakers get crossed and the output goes to both speakers.
Get it?
