Abstract (en)

[origin: DE19850868C1] The detonation circuit has a detonation voltage stage (14), connected in series with the detonation capsule (6) and a detonation transistor (22), which is caused to conduct upon reception of a detonation pulse. The detonator capsule is connected in series with a safety switch (24), e.g. a further transistor, which is supplied with a switching pulse during the duration of the detonation pulse. Both transistors may be controlled via a bus line system (2).
