Abstract
A switchgear assembly includes an indicator assembly to indicate whether a movable contact is in an open or a closed position. The indicator assembly includes an indicator body having first and second sections. The indicator body is rotatable to display the first section in the open position and the second section in the closed position. The indicator assembly also includes a drive gear having a first helical spline and coupled to an actuator of the switchgear assembly such that operation of the actuator moves the drive gear, and an elongated driven gear having a second helical spline extending along a length of the driven gear and engaged with the first helical spline of the drive gear such that movement of the drive gear rotates the driven gear. The driven gear is coupled to the indicator body such that rotation of the driven gear causes rotation of the indicator body.
