Abstract
Disclosed is a switch operator condition and position indicator mechanism for high voltage switch operators. The indicator mechanism provides a visual indication of the charged or discharged condition, as well as of the "switch-open" or "switch-closed" position, of the switch operator. Another feature of the indicator mechanism provides a visual indication of whether the high voltage switch being operated by the switch operator is in the open or closed position. The charged or discharged conditions of the switch operator are indicated by labels on a first indicator disk which rotates conjointly with the shaft used to charge the switch operator. The "switch-open" or "switch-closed" positions of the output shaft of the switch operator are indicated by labels on a second indicator disk which is operably connected to the output shaft of the switch operator by means of a linkage assembly which incorporates a spring follower mechanism which reduces the forces exerted on the operator output shaft linkage assembly and the second indicator disk during the operations of the switch operator. The labels on first and second indicator disks corresponding to the condition and position, respective…
