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