Narrative:
'Nose a/G disagree' status message appeared after takeoff. Climbing out; we consulted the QRH. Concerned that this switch controls 'stall warning and portions of the caution and warning system'; we discussed our problem with this airport's maintenance and maintenance control. They advised us to return to the departure airport and we concurred. Dispatch was notified of our return and an emergency was declared with ATC. We landed overweight; normal touchdown; long rollout; minimal braking with airfield rescue and fire fighters standing by to monitor brake temps (all ok). Arriving at gate; maintenance advised us that the nose gear air/ground switch was broken and removed the aircraft from service.
