Abstract: A switch for controlling the supply of current from a battery cell in a cell cavity to a battery terminal in a battery casing is disclosed. The switch includes a mounting base, a first buss bar connected to the mounting base and connectable to the battery cell, a second buss bar connected to the mounting base and connectable to the battery terminal, and a relay having open and closed positions. The relay includes a third buss bar that places the first buss bar and the second buss bar in contact to provide current from the battery cell to the battery terminal when the relay is in the closed position. The relay is moved into a latched open position when a first winding of a coil of the relay is energized by electricity, and is moved back into a latched closed position when a second winding of the coil is energized.
