Abstract
An electric firing device for a pyrotechnic charge in a projectile comprises a pulse generator, a pulse-activable firing control element, and means controlling the application of pulses to this element. Said means comprise an electromagnetic transducer including a primary winding receiving pulses from the generator, a secondary winding connected to said element and a ferromagnetic core coupling the windings. The core and windings are movable relative to one another, for example by mounting the windings in an inertia block, to vary the coupling and control firing upon impact.
