Abstract

In a cordless, head mounted telephone set a means of powering the radio transmission and reception unit and selecting telephone lines is provided by ganging the power and selecting switch thereof to the rotation of the microphone mouth piece.

Claims

1. In a cordless telephone headset having a housing and radio transmitter/receiver unit mounted therein in radio communication with a radio base station in contact with a telephone line, a power switch therein and a microphone in combination therewith comprising;

(a) a circular rotary wafer power switch inside the housing with an off position and a positive stop contact point which is an on position angularly displaced from said off position on an outer perimeter of said circular switch said power switch having;

(b) a wiper whose outer end has an indentation formed therein which end rotably and slidably contacts the positive stop contact point to create an on position and whose inner end is attached to a rotatable stem centrally located on the wafer portion of the switch said stem having above the wiper an insulated portion extending outward of the housing upon which are mounted spring clips which hold

(c) an insulated rod having a central passage passing perpendicularly through the rod'"'"'s longitudinal axis in which is slidably and adjustably inserted

(d) a mouthpiece arm whose first end is fitted with a mouthpiece containing a microphone which microphone is electrically connected to a second end which is fitted with a jack which jack is electrically connected to the radio unit such that

(i) when the wafer power switch is in the "off" position, the mouthpiece arm is planarly parallel to a longitudinal axis of a human head upon which is fitted the headset and the mouthpiece is located superiorly to the head and such that

(ii) when the mouthpiece arm is rotated inferiorly and forwardly anterior of the head to a plane at least perpendicular to said longitudinal axis, the wiper is simultaneously rotated to where it makes contact with the positive stop contact point thereby creating an "on" position by which the radio unit may transmit to and receive from the base station to a telephone line.

2. A cordless telephone headset as in claim 1, wherein when the mouthpiece arm is rotated inferiorly to at least perpendicular to the human head'"'"'s mouth the radio transmitter/receiver unit is continuously on.

3. A cordless telephone headset as in claim 1, wherein the forward rotation of the mouthpiece arm anteriorly describes an arc of 105°

-130°

from the off position to contact with a positive stop contact point a situated similar number of degrees on the wafer perimeter from the off position.

4. A cordless telephone headset as in claim 3, wherein the rotary wafer power switch has a plurality of positive stop contact points located in said arc.

5. A cordless telephone headset as in claim 4, wherein each of the positive stop contact points is wired to a separate radio channel.

6. A cordless telephone headset as in claim 5, wherein each radio channel is in radio contact with a separate telephone line.
