Zusammenfassung:The invention relates to a Safe-and-Arm system intended for the prevention of unintentional operation of an explosive device by interrupting a detonation train. This prevention is achieved by employing an interruptive transfer assembly (24) made of silicon, suitable for implementing in a MEMS device. The assembly includes a silicon based transfer charge carrier (24) on which a porous explosive passageway (28) is made by etching. The passageway extends between at least two ports (52,56) on the circumference of the transfer charge carrier (24). A drive means (76) can mechanically bring about at least one armed state of said detonation train.
