An electrical shunting switch assembly for use with a high continuous D.C. current electrochemical cell system, for electrically shunting or by-passing a cell of the system to permit maintenance or replacement, and then permitting stepped or gradual current diversion back through the cell. This shunting switch assembly includes a plurality of electrically parallel switch modules which comprises a vacuum switch, a series connected resistance value and switch operating means for sequentially operating the switches for current diversion. The switch modules are disposed in a matrix arrangement connected between bus connectors which are connectable across the cell, with switch modules having a low resistance value in alternating adjacent relationship to switch modules having a high resistance value. The low resistance value modules permit high shunting efficiency. The higher resistance value modules provide the capability for stepped or gradual current diversion. |
