Patent ID: 8701557

Claim:
An initiator support assembly comprising: a bridge substrate positioned within an initiator cavity, the bridge substrate comprising: a substrate base including a uniform first planar surface and an opposed second surface, a first bridge contact extending over the substrate base, the first bridge contact is substantially flush with the first planar surface, a second bridge contact extending over the substrate base, the second bridge contact is substantially flush with the first planar surface, and wherein the first and second bridge contacts and the uniform first planar surface form a continuous planar mounting surface; a flyer plate positioned within the initiator cavity and engaged along the continuous planar mounting surface in surface-to-surface contact; a barrel engaged along the flyer plate in surface-to-surface contact; an explosive charge including a charge mounting surface within the initiator cavity, the explosive charge engaged along the barrel in surface-to-surface contact; and a static coupling in surface-to-surface contact between the charge mounting surface and the continuous planar mounting surface according to a chain of surface-to-surface contact between the continuous planar mounting surface, the flyer plate, the barrel and the charge mounting surface.
