Abstract
A safety device for a sealed cell () comprising alternating positive and negative electrodes respectively connected to positive and negative current output terminals () placed in a container () having an end () that is closed by a wall. The wall of the closed end presents thinning () adapted to be torn by excess pressure inside the container, and the thinning is adapted, on being torn, to interrupt electrical conduction between the electrodes of one polarity and the corresponding current output terminal. The device of the invention is simple in design, is capable of operating at low pressures, and over a wide range of pressures, and acts as a circuit interrupter without decreasing the current density that flows in the electrical circuit.
