AIR BREAK ELECTRICAL SWITCH HAVING A BLADE TOGGLE MECHANISM

摘要

A high voltage/high current air break switch, the switch including a support frame and a blade pivotally supported by the support frame, so as to be pivotable relative to the support frame. The blade includes a load interrupter between a blade support and the distal end of the blade. And a method of operating an air break electrical switch with a swinging blade mounted on a support and having blade contacts brought into and out of engagement with a terminal with terminal contacts, and a load interrupter with contacts in a vacuum bottle, the method steps comprising turning the support to move the blade relative to the terminal, then turning the support to move the vacuum bottle electrical contacts and to move the blade contacts relative to the terminal contacts.
