<p>The disclosure relates to a method for initiating, i.e. starting, an electronically delayed-action ignition system for explosive charges, the system being entirely protected against disturbance by electromagnetic waves. According to the invention, at least a part of the pressure, heat or light energy generated from, for example, a detonating fuze (7) upon a primary detonation, is utilized for starting the time igniter (1) which in turn after a preset time-lag initiates the explosive main charge. The present invention also includes devices adapted thereto including, for instance, photocells (12), electrolytes (11) or piezoelectric transducers (8).</p> |
