Narrative:

Aircraft came from the maintenance hangar before we took our flight. Ship came to the gate with the center gear down but the center gear switch in the up pinned position. That was missed on the preflight. After gear extension the center gear green, down and locked light did not come on. We did a go around asking the tower to check if our center gear was retracted and they said yes. After the go around the switch was found in the up pinned position. Switch was then put in the down position and the center gear extended, a normal approach and landing was made. No logbook write-up because there was no malfunction only a breakdown in preflight. Human factors had a lot to do with this incident, but I'm not sure how to explain the problem. The captain, me, not a great communicator, I expect crew members to know and do their job or jobs without being told or reminded. First officer very capable but wanting to do the captain's and the so's job. The so may be a little below standard and the slack was tried to be picked up by the first officer. This, I think, led to the breakdown in the crew. And I as the captain did not stop that. After a short discussion the rest of the flight went as a normal crew.
