| 摘要 |
A detonator for explosive compositions comprises an outer jacket containing a charge of explosive detonating material which is initiated by a deflagratory primer composition ignitable by an electrical resistance element. The electrical resistance element is coupled with a photo-conductive diode or transistor to close an electrical circuit to initiate detonation in response to laser radiation transmitted to the photo-conductive diode or transistor via an optical light guide.
