Or you can do it the way the Navy does, using the "trigger" switch which is a two position momentary rocker switch. Center is "OFF", "UP" is radio, and "DOWN" is intercom.

Move it the other direction for a "on" position ( it stays there) for the intercom. In between is off. The switch is mounted in the yoke and is not that large, actually round I think. This method turns off the intercom when the pilot broadcasts to ATC, however the second pilot can still hear the conversation through sidetone. When the pilot broadcasting to ATC is through, he can switch the PTT back to "on" and talk back and forth to the other pilot. The system uses two audio panels, but I'm sure that the I-COM could be wired to work in a similar manner. The separate switch for the intercom keeps ATC from hearing the other person if he/she were talking when the pilot was talking to ATC. > >Don't count on using the intercom.
