ABSTRACT:
Disclosed is a device enabling the selective, simultaneous triggering of high energy detonators, using no sensitive pyrotechnical device, such as exploding wire detonators or slappers. The device comprises, for each of the detonators, an electrical triggering chain comprising a capacitor used to deliver energy sufficient to trigger each of the detonators. It comprises a single energy source generating a pulse and a single switch to apply the pulse to each electrical triggering chain. Means to inactivate the corresponding chain are applied before the commutation of the switch so as to make those detonators that are not to be triggered inoperative.
