ABSTRACT:
An interlock for first and second tandemly aligned circuit breaker switches which respectively have first and second external operating handles thereon oriented such that the operating handles are disposed away from each other when the switches are OFF and towards each other when the switches are ON. The interlock includes a substantially inflexible control member movably and retainably mounted relative to the switches. The control member has first and second stops, each of the stops being disposed between the operating handles for engagement therewith. The control members are constructed and arranged such that pushing the first operating handle from an OFF to an ON position pushes the second operating handle from an ON to an OFF position. The control member also includes guide structure for guiding the control member along a central groove defined by the existing structure of the switches.
