A circuit breaker operating apparatus is of the type having an enclosure, the circuit breaker mounted inside the enclosure, the circuit breaker has an operating toggle, the operating toggle has at least a trip position into which trip position the toggle is urged when the circuit breaker goes into a trip condition, the apparatus has a handle mounted on the exterior of the enclosure, the handle has a lever mounted for rotational motion relative to the enclosure. A guide is fixedly attached to the handle; a cam link, the cam link having a first end rotatably attached to the lever, and the cam link having a second end slidably attached to the guide so that as the lever undergoes rotation the second end of the cam link moves along the guide. A pin allows the second end of the cam link to slide along the guide in response to the toggle as the toggle is urged into the trip position by the circuit breaker going into a trip condition so that the position of the lever indicates that the circuit breaker is in a trip condition.
