MEMS arm fire and safe and arm devices

摘要: Miniature arm fire and safe devices include an electrically operated pyrotechnic initiation device (5) to generate a detonation wave upon command movable pressure barrier (9) that blocks propagation of the if is not intended be fired opens window (12) transfer externally device. The may in alternate embodiments subsonic flame front or supersonic shock wave, respectively. An electromagnet (7) serve move barrier. Detonation waves output from have application igniting explosive train, either directly indirectly, latter by operating electrical switch. In device, automatically prevents when power removed barrier, once moved out way, remains even removed. Various forms miniature single operate switches are described foregoing devices.
