摘要: A switch device for one-time use in conducting very high currents comprising a silicon substrate on which is deposited amorphous or polysilicon strip extending as bridge between first and second spaced-apart metal contacts the substrate. Also same opposite sides of spaced from it are set voltage contacts. When applied across contacts, no current flows until trigger made to flow through bridge, being sufficiently large vaporize creating plasma cloud. The plasma, highly conductive, allows present invention finds special application part detonation system explosive ammunitions. This specification discloses various modifications above structure achieve desired performance characteristics.
