wiring question

Purveyor of Thought...
Does anyone know how to wire some type of a switch that would allow you to switch from headphones back to internal speakers on an iMac without having to disconnect the headphone jack from the back of the iMac…

I am thinking of somehow creating a circuit that will make the iMac think that nothing is plugged in so it will play thru it's default built in speakers but when I push a button it will go to the headset..

Any ideas ?? it would probably involve a DPDT switch of some kind, just not sure how to wire it to fool the iMac into thinking there is nothing plugged in.
