## Discrepancy

WHILE ENROUTE, THE CREW CALLED MAINTENANCE CONTROL AND STATED THE FIRST OFFICER'S MICROPHONE'S PUSH TO TALK SWITCH WAS NOT WORKING.  FLIGHT 4169 DIVERTED TO CAK WHO HAD THE PART IN STOCK.  MAINTENANCE THEN INSPECTED AND REPLACED THE SWITCH IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 23-00-00.  OPERATIONAL CHECKS WERE PERFOMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
