An electrical switch for efficient, high continuous current carrying operation, with at least one movable contact for effecting current interruption. The ambient pressure within the volume defined by the electrical switch body is maintained at or is reducible during contact opening to between 10-1 to 102 Torr to minimize contact erosion. A preferred electrical switch is a hermetically sealed, low voltage d.c., device for shunting an electrolyte cell. The sealed switch module has a reduced pressure atmosphere of inert fill gas at a pressure of from 10-1 to 102 Torr.
