The embodiments of the switch described herein include latching and locking systems so as to retain the rod of a vacuum bottle in a determined, open or closed, position, the systems being driven and controlled by the same means that cause the movable portion of the vacuum bottle to move, or by the disconnector itself.

Latching and locking device inside a switch or a circuit breaker

This interrupter device includes a parallel branch () in which a vacuum switch chamber is connected for breaking current. The branch is inactive in normal operation, with current flowing in it only when the disconnector () has started its opening movement, by progressive transfer of the current from the main power line () to the branch (). Since the vacuum switch () is generally at rest, it no longer needs to be dimensioned to satisfy stringent electrical and dielectric requirements for normal operation.
