UNSPSC 39122235: Modular wiring system switch

UNSPSC 39122235 Modular wiring system switch, a Commodity code, covers the procurement of electrical switching and control components used in transit, facilities management, and infrastructure maintenance. State and local governments buy these switches primarily as replacement parts and maintenance supplies for transit systems, correctional facilities, schools, and county departments. Transit authorities and regional transportation districts represent the dominant buyer category, with transit agencies in Texas soliciting switches, solenoid lock controllers, receptacle covers, and related electrical components on a recurring basis; school districts, county sheriffs' offices, and state corrections departments also purchase switching equipment and electrical supplies through individual and multi-year contracts.

Dallas Area Rapid Transit Authority (DART) drives much of the recent activity under this code, having posted at least four relevant solicitations between May and October 2026—including bids for a solenoid lock switch with controller transformer (Opportunity #2099242, due May 20, 2026), a power converter (Opportunity #2100940, due October 16, 2026), an entire dual fixture light assembly (Opportunity #2100939, due October 20, 2026), and receptacle/switch covers (Opportunity #2101441, due October 20, 2026)—all with FOB Destination terms, Net 30 payment, and strict timely-delivery requirements. Beyond DART, Northside Independent School District (San Antonio) sought sealed bids for electrical equipment, parts, and supplies (IFB, due July 1, 2026); Hillsborough County (Florida) issued a two-year, $519,787.19 contract for Schneider brand electrical components (ITB, due June 18, 2026); and Orange County Transportation Authority (California) requested industrial electrical supplies under RFQ 250243 with a $10,000 annual budget. Activity concentrates in Texas and Florida, with secondary activity in California and Georgia; DART's repeated solicitations and tight delivery windows signal sustained component consumption in transit infrastructure maintenance.
