ABSTRACT:
A headset assembly is described, of the type which includes a headband with earphones for delivering sound to the wearer, a microphone into which the wearer talks, and a "push-to-talk" switch that is operated when the wearer wishes to talk, whcih facilitates operation of the switch. The switch (24) has an actuator part (30) extending from one of the sides of the headset, such as the left side, to a location above the left shoulder of the wearer. The wearer activates the switch by lifting his left shoulder to press on the actuator part of the switch. The switch is preferably closed by depressing the actuator part, and extends in a downward-outward direction at an angle of about 30.degree. from the vertical, so the natural lifting of the shoulder causes the shoulder to move along the direction of depression of the switch actuator part.
