<p>PURPOSE: To urgently cut off an electric current to load at the time of a vehicle collision in a simple constitution. CONSTITUTION: A relay 10 as a by-pass means operated according to an output of an air bag sensor to by-pass a current to the input end of a junction box 5 through an earth is provided in the interior of the junction box 5. Accordingly, at the time of a vehicle collision, a current from a battery 3 through a second fusible link 4 can be let flow through an earth by the operation of the relay 10 according to the output of the air bag sensor, so that the second fusible link 4 can be forced to generate heat and fused, and a current to each load 7 can be surely cut off in a more simple constitution as compared with that of the prior art.</p> |
