ON ACCELERATION FOR TAKEOFF THE CREW RECEIVED A TAKEOFF CONFIGURATION WARNING HORN AT 100KTS, PRIOR TO ROTATION.  TAKEOFF WAS ABORTED WITHOUT INCIDENT.  THE AIRCRAFT RETURNED TO THE RAMP.  WHILE TROUBLESHOOTING THE PROBLEM CORRECTED ITSELF.   DETERMINED THAT THE RIGHT SPEED BRAKE INBOARD PANEL STOW SWITCH MUST BE AT FAULT.  REMOVED AND REPLACED SWITCH.  SIMULATED FAILURE AND IT DUPLICATED THE SYMPTOMS.  COMPLETED TESTING AND PERFORMED TEST FLIGHT SATISFACTORILY.
