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.

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 (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?

Looks like that will work. If I remember correctly, the tip on the plug is the left speaker channel.
And pay special attention to what typefighter01 said about the volume on the headphones. It can be very hard on your ears to plug in the headphones with the volume turned all the way up.

otsep,
Made a quick diagram for you to refer to. Just unsure on how you are powering your speakers and if you need stereo or not. But yes, that Neutrik jack will work fine.

Thanks for the support guys! :notworthy:
For clarification, they're a set of 2.1 powered computer speakers.
I think I'm going to add headphone jacks for the line coming from PC Audio Out and the Speaker output. Do you think thats a bad idea?
-
If the 3.5mm cable for your powered 2.1 PC speaker set is long enough, you can just splice in the jack (see pic). If it is not long enough, buy yourself a 3.5mm male extension cable and just snip the end off of it.

I think you are suggesting that you want to add headphone jacks on each end to keep it clean looking? If so, that's fine, it will sound the same either way.
One note...sometimes the PC speaker line out has different impedance level than the headphone jacks, so just test your headphones in the PC out jack first to be sure they will provide enough power (sound good). Sometimes the jacks are basically the same and sometimes they have different output specs (straight line out or amplified for headphones). Just plug your headphones in and listen to see if they sound o.k.

I have the speakers plugged into the headphone port now with the volume on the control unit turned down a bit. This has allowed me to control the volume easily from the PC instead of the volume know on the sub.

Perfect...sounds like you have it all sorted out. Let us know how you make out :cheers:
