Abstract

Pressure-isolating bulkhead structures with integrated selective electronic switches circuitry are provided. The pressure-isolating bulkhead structure may be a single unit having the integrated electronic switch circuitry, as well as an electrical connector that includes at least one of a wire and a pin contact. Such integrated selective electronic switch circuitry may be fashioned within a self-contained, inner pressure-isolating enclosure body. Such inner pressure-isolating enclosure body may be produced about the selective electronic switch circuitry such that the inner pressure-isolating enclosure body and switch circuitry are produced as a unit, which can be easily placed within a variety of bulkhead structures, and subsequently within a perforating gun.
