ABSTRACT:
An improved disconnect/ground switch assembly for use in conjunction with a high voltage DC power supply is disclosed. High voltage rectified DC power is provided on a conductor through an insulating bushing. An electrically conductive contacting mechanism mounted on the end of the bushing and in electrical contact with the conductor serves as a source of power for driving a pair of loads through respectively associated switching contact members. Actuating mechanisms for switching either or both of the switch contacts to associated grounded contacts are shown. Opposed apertures in the switch housing are adapted for receiving load driving conductors positioned in conductor conduits. A transparent covering of a viewing aperture for observing the positions of the switch contacts is shown.
