A two-rotor, three-position indicator for a valve actuator is connected to receive rotary input from at least two independ- ently operating rotors connected inside the geared limit switch of a valve actuator. Individual drive lugs moved interconnected gearing to cause a pointer to indicate whether the valve stem is open, closed or in-between those two oppositely disposed limits.
