Abstract (en)
[origin: FR2880110A1] The primer has an electric shunt (7) which is disposed in parallel with an electrothermal bridge (4). The electric shunt is controlled by an electronic circuit via a line (6), to permit a selection between closed and open states. The electric shunt has a low electric resistance so as to stop ignition of the primer, in the closed state. The shunting unit has a high resistance in the open state.
