ABSTRACT:
A vacuum switch assembly which is connectable as a shunting switch across the electrodes of an electrochemical cell, in which a plurality of electrical parallel current paths are provided through a plurality of parallel vacuum switches with separate electrical bus conductors extending from each switch contact. The vacuum switch layout is particularly adapted to permit bus conductor paths to the electrochemical cell which minimize stored induction energy which must be dissipated. The vacuum switch operating mechanism provides for approximately simultaneous switch operation with means for adjusting the individual switch openings. The switch assembly is compact and portable for correction to any one of the series cells in a plant.
