A gas charged accumulator includes a gas chamber and a hydraulic reservoir on opposite sides of a movable member. A fill passage for pressurizing the gas chamber includes a movable operating device for operating an indicator when the accumulator is substantially discharged. Gas flows directly past the indicator operating device when the gas chamber is pressurized through the fill passage. A normally closed switch assembly is mounted in the fill opening outwardly of the indicator operating device subsequent to pressurization of the gas chamber. The indicator operating device holds the switch assembly in an open position when the accumulator is charged and provides closing of the switch when the accumulator is substantially discharged.
