Means for triggering an electrical fuse in a power supply circuit

Means for triggering an electrical fuse in a supply circuit of which is arranged in a motor vehicle load, characterized in that an opposed grounded electrical conductor (3) and a positive conductor (4) are arranged in the supply circuit in the motor vehicle so that by a in a accident acting force, the two conductors (3, 4) are short-circuited low impedance and by the two low resistance short-circuited conductor (3, 4), the electrical and electronic components of the supply circuit and the electrical load (1) from the power supply source (6) are separated and substantially all of the supply current is fed to the fuse (2).
