A switch assembly including a vacuum interrupter having a fixed contact and a movable contact, an actuator operable to move the movable contact, and a drive rod assembly coupled to the movable contact and the actuator. The drive rod assembly includes a male part and a female part where the male part is inserted into and coupled to the female part. One of the male part or the female part includes a conductor that provides an electrical connection between the male and female parts and one of the male part or the female part includes a locking ring that snap fits into a groove in the other male or female part.

Snap together assembly for vacuum interrupter drive rod

A switch assembly for high voltage applications, where the switch assembly includes a traditional mechanical switch and a triggered gap device electrically coupled in parallel. The mechanical switch includes a first switch contact and a second switch contact, where one or both of the first switch contact and the second switch contact are movable to engage and disengage the first and second switch contacts to allow or prevent current flow therethrough. The triggered gap device includes a vacuum enclosure, a first stationary contact positioned within the enclosure and a second stationary contact positioned within the enclosure, where a gap is defined between the first and second stationary contacts. The triggered gap device further includes a plasma control device that allows creation of a plasma in the gap that causes an arc between the stationary contacts on the order of micro-seconds that allows current flow between the contacts.
