UNSPSC 39122246: Electrical potentiometer switch

A three-terminal resistor with a sliding contact that forms an adjustable voltage divider. If only two terminals are used, it acts as a variable resistor or Rheostat.

UNSPSC 39122246 Electrical potentiometer switch is a Commodity code that encompasses electrical switches, controls, and related components procured by state and local transit authorities, county governments, school districts, and municipal departments for maintenance, repair, and emergency operations. State and local buyers under this code are acquiring dual fixture light assemblies, outlet covers, solenoid lock switches, traction power fuses, power converters, push-button inventory switches, and standardized electrical component parts for use in transit systems, facilities, and infrastructure. Dallas Area Rapid Transit Authority (DART) emerges as a dominant repeat buyer, issuing multiple bids for individual switch and electrical component line items on compressed timelines. Issuing bodies span transit authorities, county sheriffs' offices, independent school districts, county governments, and municipal departments. Work solicited includes both individual component procurements and indefinite-delivery indefinite-quantity (IDIQ) contracts for ongoing electrical supplies and maintenance materials. Representative procurements emphasize tight delivery schedules as a material contract requirement, with sellers facing default termination for failure to meet specified delivery time and rate.

Recent activity concentrates heavily in Texas, with DART (serving Dallas County) posting five separate solicitations between May and October 2026 for specific electrical components and assemblies, all requiring FOB Destination shipping with freight included and Net 30 payment terms. Hillsborough County Board of County Commissioners (Florida) solicited an estimated $519,787.19 two-year contract for authorized Schneider Electric components with a June 18, 2026 deadline. Northside Independent School District (San Antonio, Texas) requested sealed bids for electrical equipment, parts, supplies, rentals, repairs, and services with a July 1, 2026 deadline. Orange County Transportation Authority (California) issued an RFQ for industrial electrical supplies under a $10,000 annual budget with delivery to two facilities in Garden Grove and Santa Ana. The City of Tampa (Florida) requested quotes for a specific G.E. push-button switch component with a five-day delivery requirement. Geographic concentration appears strongest in Texas and Florida, with additional activity in Georgia (City of Atlanta airport switch replacement) and California (Orange County and Sourcewell cooperative law enforcement equipment procurement). DART's repeated, rapid-turnaround component bids and the Hillsborough County two-year standardized parts contract indicate sustained demand for electrical components tied to transit system and infrastructure maintenance cycles.
