A MOC operator structure for a vacuum circuit breaker includes a cam coupled to an operating shaft of the circuit breaker, a follower in engagement with the cam, a first lever coupled with the follower, free-floating spring structure associated with the first lever, a second lever, a linkage structure coupled with the second lever and constructed and arranged to be associated with a breaker-panel interface for moving auxiliary switches, and movable cable structure operatively coupled between the first and second levers. The first lever and spring structure are configured such that when the contacts are closed, movement of the cam via the operating shaft drives the first lever to a maximum position compressing the spring structure, prior to any movement of the cable structure, and wherein force of the spring structure moves the cable structure and thus the second lever, causing movement of the linkage structure.

The present invention relates generally to handle stops. More particularly, the invention encompasses a positive handle stop for a switch. The positive handle stop for a switch, such as, a safety switch, prevents the handle of a switch from returning to the shipping position once the switch is turned ON. The invention also includes a shipping position for the inventive handle so as to reduce the size of the packaging need to ship the switch apparatus.
