Detroit Switch Inc.

Detroit Switch Inc., a Pittsburgh-based manufacturer of pressure, thermostatic, and temperature industrial control switches, operates as a Subchapter S Corporation competing exclusively as a prime contractor in full-and-open federal procurement with no small business set-asides across the vast majority of its award footprint, though it holds a small portfolio of Total Small Business set-aside orders from the Defense Logistics Agency Land and Maritime.

The company's federal business is monolithic and concentrated in a single customer: the Defense Logistics Agency Land and Maritime funds 96% of the 4,653 awards in the source data, representing $68.8 million of the $70.8 million combined potential value across the entire award footprint. DLA Land and Maritime has issued Detroit Switch Inc. roughly 4,200 purchase orders and delivery orders for individual switch components, supplemented by approximately 15 single-award indefinite delivery contracts with $250,000 to $350,000 ceiling values apiece. The firm executes small, discrete delivery transactions under those IDIQs—typical task orders range from $1,500 to $40,000—supporting DLA's inventory and maintenance operations for military vehicles, vessels, and aircraft. Secondary customers including Naval Supply Systems Command, Defense Logistics Agency Aviation, and the Department of the Navy account for only 4% of award count and represent negligible dollars.

Detroit Switch Inc.'s capability footprint is narrow and commoditized: it manufactures pressure switches, thermostatic switches, and temperature switches classified under NSN prefixes 8511 and 5930. The portfolio carries PSC code 59 (Electrical/Electronic Equipment Components) and maps predominantly to NAICS 332919 (Other Metal Valve and Pipe Fitting Manufacturing) and 335313 (Switchgear and Switchboard Apparatus Manufacturing). Representative recent awards include a $38.9 million delivery order for thermostatic switches (October 2025, DLA Land and Maritime, Total Small Business set-aside), a $32.4 million pressure switch purchase order (July 2025, DLA Land and Maritime), and a $29.1 million pressure switch purchase order under Total Small Business set-aside (July 2025, DLA Land and Maritime). The company holds no parent contract vehicles outside single-award indefinite delivery contracts awarded by DLA; all work flows through DLA's procurement vehicles. Recent IDIQs awarded include contracts with $250,000 ceilings (August 2025, July 2025, June 2025) and contracts with $350,000 ceilings (April 2026, March 2026, January 2026).

Activity has declined sharply. The source shows 439 awards in 2022, declining to 73 awards through April 2026—a 83% drop year-to-date. The recompete cliff is modest: only 59 awards with ultimate completion within the next 24 months carry a combined potential value of $610 thousand. The company executed one federal subcontract: a sub-award to Electric Boat Corporation on the SSN 804 submarine construction program (June 2024), indicating minimal integration into primes' supply chains.

Detroit Switch Inc. competes in full-and-open procurement. It does not hold 8(a), HUBZone, SDVOSB, WOSB, or other SBA designations. The source identifies Post's Inc. as a named subsidiary; no corporate strategy or capability relationship is stated.
