The invention describes a battery having a housing, at least one individual cell which is arranged in said housing and has at least one positive and at least one negative electrode and also at least one positive and/or negative pole stud which is routed through the housing. The battery comprises at least one electrical switch which can be pneumatically operated, changes its switching state in the event of a pressure increase within the housing above a threshold value and, in the process, interrupts an existing electrical connection between at least one of the pole studs and the at least one electrode which is connected to said pole stud. The battery is distinguished in that it comprises a resetting device with which an electrical connection which is interrupted as a result of a change in the switching state can be re-established without it being necessary to open the housing for this purpose. The invention also describes a pole stud which is suitable for the described battery. Said pole stud comprises a head with two opposite flat faces, and comprises a shaft which extends out of one of the flat faces and has a free shaft end, and is characterized by a hollow space within the head, a gas-impermeable diaphragm which bounds the hollow space, and also a passage hole through the shaft, which passage hole issues into the hollow space. |
