Switch Replacement Parts
The three different types of counters which have been used in manufacturing the VBM™ switch include a counter attached to the manual operating handle cover, the internal five digit counter, and the externally visible six digit counter. The five and six digit counters are shown above. The handle cover counter is not available.
Five-Digit to Six-Digit Position Indicator Counter Conversion
During switch overhauls at the Vacuum Electric Switch Co.™ old switches without externally visible counters are modified to use the new externally visible six digit counter with a position indicator. This upgrade makes it easier to track switch operations for purposes of scheduling maintenance. The modification can only be done in the shop because it requires welding in a boss and re-machining the switch mechanism casting. The window for the new counter and position indicator is sometimes located where the existing name plate is located. In this instance the Vacuum Electric Switch Co. also replaces the old name plate with a new name plate having the old serial number.
