<p>When the pyrotechnical cartridge or motor (5) is actuated by electrical ignition from its head (5c), it pushes back the insulating piston (3) which separates by shearing the intermediary connection portion (1b) of the destructible lead (1) and pushes it back into the bore (1e) with the rod (9) of which the conic end (9a) wedges into the plug (10) for forming brake. The fuse cartridges (13) cut off safely the circuit. Application to electric circuit shut off, for example under the effect of overcurrent detectors. </p> |
