An initiator assembly includes an initiator housing having an initiator cavity and a housing orifice edge. A bridge substrate is positioned within the initiator cavity, the bridge substrate includes a substrate base including a uniform first planar surface and first and second bridge contacts flush with the uniform first planar surface. The first and second bridge contacts form a continuous planar mounting surface. An explosive charge and a flyer plate are within the initiator cavity, the flyer plate interposed between the explosive charge and the bridge substrate. A plunger head is telescopically received in the initiator cavity and includes an anchoring cylinder face having a face perimeter and extends between first and second face ends. The housing orifice edge is anchored to the anchoring cylinder face at a position between the first and second face ends and extends around the face perimeter.
