Charlie may have been under the impression that if the entire station filled under water that the group would not be able to communicate with the boat, he only had Desmonds premonitions that if he didn't die by drowning after flipping the switch that Claire wouldn't get off the island, so he accepted the sacrifice and closed the door saving the rest of the station so Claire and the baby could be saved.
