UNSPSC 39122225: Mercury switch

UNSPSC 39122225 Mercury switch (Commodity) describes electrical switching components that state and local governments procure for transit infrastructure, facility maintenance, law enforcement systems, and educational facilities. Recent activity shows transit authorities and school districts sourcing individual switches, solenoid lock switches with control transformers, switch assemblies, and related electrical components as part of ongoing maintenance and repair operations. Dallas Area Rapid Transit Authority (DART) has posted multiple solicitations on this code—for solenoid lock switches with controller transformers, dual fixture light assemblies, outlet covers, and power converters—indicating regular equipment replenishment for a large regional transit system. Beyond transit, Northside Independent School District in San Antonio and Chatham County Sheriff's Office have also used related electrical component codes, signaling demand across school districts and public safety agencies. The issuing bodies mix transit authorities, school districts, county sheriffs' offices, and municipal utilities, suggesting the code captures critical infrastructure replacement and scheduled maintenance spending across diverse jurisdictions.

Recent opportunities concentrate in Texas, particularly Dallas and the surrounding region through DART, with secondary activity in Florida (Tampa, Chatham County, Orange County Transportation Authority, Hillsborough County) and Georgia (City of Atlanta). DART has posted multiple related solicitations in October 2026—solicitation 2100939 for a dual fixture light assembly due October 20, 2026; solicitation 2101441 for a receptacle/switch cover due October 20, 2026; and solicitation 2100940 for a power converter due October 16, 2026—all requiring FOB Destination pricing, on-time delivery as a material performance term, and Net 30 payment terms via BONFIRE portal registration. Northside Independent School District issued IFB2026098 for electrical equipment, parts, supplies, rentals, repairs, and services (bids due July 1, 2026), and Hillsborough County Board of County Commissioners procured Schneider brand electrical components under ITB-26-00277 (bids due June 18, 2026) with an estimated contract value of $519,787.19 over two years. Orange County Transportation Authority issued RFQ 250243 for industrial electrical supplies with a $10,000 annual budget. The code shows active procurement momentum in the Southeast and Southwest, driven primarily by regional transit authorities managing aging infrastructure.
