A position indicator assembly is provided for a levering assembly of an electrical switching apparatus, such as a circuit breaker. The levering assembly includes a drive shaft and a racking member movably coupled to the circuit breaker housing. The drive shaft cooperates with the racking member to facilitate racking the circuit breaker into and out of a cassette. The position indicator assembly includes a number of indicator gears cooperating with the drive shaft, an indication rack cooperating with the indicator gears, and an indicator cooperating with the indication rack to provide a visual indication indicative of the position of the circuit breaker with respect to the cassette. When the circuit breaker is moved with respect to the cassette, the drive shaft pivots. In response, the indicator gears move, thereby moving the indication rack and the indicator in order to provide the visual indication.
