ABSTRACT:
An electrochemical cell, such as a rechargeable cell, employing switch means comprising a spring member biased to electrically connect one of the cell's terminals to one of the cell's electrodes and wherein a pressure responsive movable member is designed to pivot the spring member on a fulcrum member to break the electrical connection between the electrode and the terminal when the pressure within the cell exceeds a predetermined level and wherein said spring member is isolated from the active components of the cell.
