An electrical circuit interruption device (fuse) having an inherently conductive polymer, preferably a polypyrrole, as its actuating element. Such fuses (A) "blow" substantially faster than conventional metal fuses (B) at low overload currents. Oxidising dopants such as perchlorate or picrate ions may be used to enhance the circuit-breaking effect, and the fuses, whether or not so doped, may advantageously be used as electrical primers ("bridge wires") for pyrotechnic devices. |
