<p>A plug adapter (10) that allows any headset to be used with any handheld two-way radio is disclosed. The adapter has a body having first (20) and second (30) ends. The first distal end is a jack (20), adapted to receive a headset plug. The jack has a ring electrical contact (22) and a conductive tip contact (24) to mate with the conductive tip of the headset's plug. The electrical contacts in the jack are electrically isolated from each other. The second distal end of the adapter forms a plug (30) having at least a conductive ring and a conductive tip. The conductive ring (16) and conductive tip (18) are electrically isolated from each other. The adapter electrically connects the jack's ring electrical contact (22) to the conductive tip (18) of the adapter's plug and the jack's conductive tip contact (24) to the conductive ring (16) of the adapter's plug.</p> |
