A bidirectional clutch with opposing output drives mounted over an internal support shaft, and a bidirectional clutch jaw positioned between them. The clutch jaw has opposing cam surfaces which cooperate with cam surfaces on the inside edge of the output drives. The clutch jaw further has forward and reverse driving surfaces which are associated with forward and reverse driving surfaces on the output drives. The clutch jaw moves between the output drives and engages only one output drive at a time. When the clutch is reversed, the cam surface on the output drive which was being driven imparts lateral force to the clutch jaw which moves it away from the active output drive to the inactive output drive. The clutch jaw disengages from the active output drive and then begins rotating the inactive output drive in the reverse direction.
