Title: Stationary contact structure for high voltage gas blast circuit interrupter with deformed slotted contact finger configuration

Abstract: A stationary contact structure for a gas blast circuit interrupter consists of a conductive hollow cylinder which is slotted to define contact fingers, and the ends of the contact fingers are inwardly deformed so that the ends of the fingers closely abut one another to prevent inward deflection of the contact fingers to a degree which would exceed their elastic limit.
