ABSTRACT:
A high-voltage, blast-actuated power switch is disclosed in which non-arcing edges are formed on a bridge conductor when the conductor is blasted. Upon blasting, the bridge conductor bends forming edges having a large radius of curvature. When the bridge conductor is blasted, an element of the bridge conductor moves in the axial direction away from the other element of the bridge conductor, thereby increasing the separation between bridge conductor elements. The axially movable bridge conductor is held in its new axial position causing the bridge conductor elements to remain separated.
