All, I used a DPDT switch, and wired it so that when it is in CW position the Mike jack is disconnected from the mike amp's audio input. No need to unplug the mike for CW mode. The Key jack acts as Key in CW mode and acts as PTT in SSB mode, and of course the mike jack is connected to the mike amp's audio input for SSB mode.
