  • Explosively activated impact switch with interlocking contacts
    Patent number: 4674406
    Abstract: A method and apparatus for detonating an explosive in response to the dettion of a remote explosive without damaging any components positioned intermediate the two explosives. An impact switch having contact elements that permanently interlock when activated is positioned adjacent to one of the explosives. A power supply is connected to the impact switch, and the output from the power supply is connected to the detonator for the second explosive. When the first explosive is detonated, the contact elements of the impact switch close, permanently interlocking. This completes and activates an electrical circuit with the power supply that sends current to the detonator of the second explosive to initiate detonation of the second explosive.
