Audio jack with ESD protection |
(57) A plug-and-jack for use with an electronic device that is configured to ensure circuitry
of the device is protected from electrostatic discharge. In one case, the jack is
an audio jack designed to protect high gain circuitry of the device against electrostatic
discharge from the leads of an audio plug. The jack includes a mechanical switch that
only connects the high gain circuitry to the appropriate portion of the audio plug
once the audio plug is fully inserted. At the same time, the mechanical switch also
connects the high gain circuitry and corresponding portion of the audio plug to an
electrostatic discharge circuit.
