Narrative:

Microphone switch became disabled and stuck in the 'hot' position. This disrupted center frequency for approximately 3 mins. Cockpit conversations were broadcast over frequency for this period of time. Once discovered (due to absence of conversation over the radio) we jiggled yoke switch to unstick it and deselected the captain's microphone selector. Center was upset and we apologized. Alternate audio panel intercom switch was used for the rest of the flight and maintenance in fll was advised of the problem. Dispatcher was also alerted.
