An electrochemical cell is disclosed having an internal circuit which is interrupted by a switch that is responsive to both excessive cell temperature and pressure. The switch preferably comprises a bimetallic strip mounted in the space between the cell cover and case and is electrically connected between one of the cell electrodes and its associated terminal. The bimetal undergoes temperature-induced distortion to open-circuit the cell and is additionally responsive to the movement of a pressure diaphragm, which forms a part of the cell case wall, to open-circuit the cell in the event of excessive pressure. The cell is automatically reactivated when the excessive condition has dissipated.
