Abstract: A connector plug having special utility in the electrical musical instrument field is disclosed. The plug comprises a body having first and second elongated electrodes extending outwardly therefrom. The first electrode is slideably disposed in the second electrode and electrically isolated from the second electrode along the length thereof. Means are provided in the body for urging the distal ends of the first and second electrodes into electrical engagement in the rest position. When the plug is joined to an associated jack, however, the distal ends of the electrodes are caused to disengage so as to electrically isolate the electrodes from each other. By the use of the device of the present invention, problems of undesirable noise being generated when activating an electrical musical instrument or like device is substantially eliminated.
