HEADSET CONNECTORS AND CONTROLS
The connectors and controls for the TTH and TTH Series 2 headsets are integrated
into the cable/microphone assembly normally attached to the left earcup of the
headset. The assembly may be mounted on the right earcup if desired.
The control module on the cable/microphone assembly has a three-position push-to-
talk (PTT) switch as well as a two-position talk-thru circuit (TTC) switch as shown in
Figure 2.0b and 2.0c. The PTT switch is mounted on the face of the control module
and is spring loaded to the center (disabled) position with a momentary PTT position
and latched live intercom position. The control module may also be connected to the
communications microphones typically installed on protective masks.
When the
external microphone connector is connected, the control module automatically
disengages the headset boom microphone to receive signals from the external
microphone.
