LEACH INTERNATIONAL CORP

Leach International Corp specializes in the design, manufacturing, and supply of electromechanical relays and industrial control systems for mission-critical defense and aerospace applications. Their technical expertise centers on precision electromagnetic relay manufacturing, including compliance with military specifications such as MS27751, and the production of high-reliability switching components used in avionics, vehicle control systems, and battlefield electronics. The company demonstrates deep familiarity with ruggedized component standards and defense-grade quality assurance protocols, serving as a trusted supplier of mission-critical control elements where environmental durability and signal integrity are paramount. Their capability extends to supporting complex electro-mechanical assemblies requiring tight tolerances and traceable manufacturing processes under stringent government specifications. The contractor maintains a consistent and primary relationship with the Department of Defense, supplying components for ground, air, and maritime platforms through direct procurements and logistics channels such as DLA Land and Maritime. Work for these agencies involves the provision of standardized, government-specified relays and control devices essential for system functionality in harsh operational environments. The recurring nature of these awards indicates a sustained, long-term supplier relationship built on reliability, regulatory compliance, and on-time delivery of defense-critical hardware. The company’s industry focus is firmly rooted in NAICS 335314—Relay and Industrial Control Manufacturing—with secondary involvement in printed circuit assembly, electronic component manufacturing, and aerospace subsystems. This positions them as a niche supplier within the defense electronics supply chain, specializing in electromechanical switching solutions rather than pure electronics fabrication. Their vertical specialization lies in ruggedized, military-specified control hardware used in tactical systems and vehicle platforms. Leach International Corp operates as a small business with a single-location presence in Buena Park, California. While they hold no formal government certifications, their sustained contract activity with DoD and DLA signals strong credibility within the defense industrial base. Their market positioning is that of a specialized, precision manufacturer serving high-assurance government programs requiring certified electromechanical components.
