ABSTRACT:
A gas-insulated switch has separable contacts disposed within a chamber-forming cylinder. The arc drawn between the contacts on opening provides pressurizing of the arc-extinguishing fluid in the chamber, while additional pressurization is provided by an interlocking member which has an interlocked movement with the contacts during the opening operation.
