Beschreibung
Zusammenfassung:	The invention is directed to a pressure activated current interrupt assembly for cells, particularly alkaline cells. The current interrupter is located at the closed end of the cell's housing. The current interrupter assembly comprises an electrically insulating member in proximity to the terminal at the closed end of the housing. The insulating member is in physical communication with a deflectable member formed from the cell's housing. When gas pressure within the cell builds up to exceed a predetermined value, the deflectable member deforms causing the insulating member to protrude beyond the extremity of said cell terminal, thereby preventing electrical contact between said terminal and the terminal of another cell or electrical device.
