Abstract:
A composite electrical switch assembly for use with pad mounted switch gear located within an electrical cabinet, said cabinet having a first inner switch gear confinement area and a second outer electrical component confinement area, said first and second confinement areas separated by a dead front barrier, said composite electrical switch assembly comprising a switch arm, a terminal, and an integrated bushing component,said switch arm selectively positionable from an open non-conducting position and a closed electrically conducting position, said switch arm connecting a first electrical circuit to said terminal in said closed position,said integrated bushing component having in a unitary member, an axially extending electrically conductive inner core and an electrically insulated housing, said inner core conducting a primary electrical current from said terminal located within said first inner switch gear confinement area, through an opening defined in said dead front barrier, to said second outer electrical component confinement area, said integrally formed electrically insulated housing receiving an electrical arc extinguishing pump assembly therein, said arc extinguishing pump conductively biased against said terminal and providing a movable electrical connection between said terminal and a probe connector in conductive attachment to said switch arm.
