DIY Audio Switch or Buy

I'd like to make a pushbutton toggle this DPDT setup to toggle between the built in cab speakers and headphones.

I threw this together although I'm not sure if it's overkill or am I better off buying the product linked under it.


DPDT Signal Relay Module

Typefighter01:
If you want to have your cab speakers (speaker) work all the time, except when you insert headphones into the headphone jack, you can just use these http://www.ebay.com/itm/Mono-Jack-Socket-2-5mm-or-3-5mm-Switched-Loudspeaker-Cut-out-/120820192178. Pay attention to the jacks that say "Switched Loudspeaker Cut Out". They are designed to allow an audio signal to pass through them until the signal is broken by inserting the headphone plug. Shop around, you should be able to find them for a buck or two with free shipping (yes, the ones in my example are mono, but I am sure they are offered in stereo).

Be careful when using headphones with an unknown amplified signal. Depending on the amount of amplification, you could hurt your ears or damage the headphones and/or amp.

Let us know what the "audio in" is in your diagram (should be labeled "audio out") and we can go from there.

The "Audio In" is for the circuit, but it's actually the audio out from the computer(configured as headphones).

Something like this?

Here is what I drew up.  Am I completely off base?
