3.5mm headphone jack

hellp, on a sterio 3.5mm audio jack, is the back pin the ground? (and the other 2 are left audio and right audio??)

the reason i ask is because i want to have a switch on 4 or 5 different sockets so i can turn each one on/off

i plan to do it like the ckt attached

assuming the black + green go to the left channel and right channel and the yellow to the back (end of plug)

You can't just switch one wire (the ground?). You need to switch both channels on and off.
Disconnecting only the ground wire still leaves the headphones connected to both channels where they will still play a strange out-of-phase "difference" signal.
Look at the plug and jack in my sketch to see which terminal connects to what.
