UNSPSC 39121908: Switch lockout

UNSPSC 39121908 Switch Lockout, a Commodity code, covers electromechanical switching components and safety devices used in utility, municipal, and facility infrastructure—particularly mercury float switches, soft starters, contactors, and related electrical control hardware that state and local governments procure for water treatment, wastewater reclamation, transit systems, and facility operations. Recent opportunities show mixed scope alignment: most solicitations tagged to this code actually seek broader electrical equipment, parts, and services rather than lockout switches specifically, though two procurement records explicitly name mercury float switches and electrical control components central to pump and generator systems.

Issuing bodies are predominantly municipal water districts, county utilities, and school districts, with standout repeat buyers including Hillsborough County Water Resources Department (two separate float-switch and contactor procurements in January–February 2026) and municipal water utilities across Florida and California. Geographic activity clusters in Florida (Hillsborough County, Orange County, Monroe County), California (West Basin Municipal Water District, Eastern Municipal Water District), and scattered single opportunities in Texas (San Antonio school district), Oregon (Salem), Georgia (Bibb County schools), and Minnesota (Sourcewell cooperative serving Washington state jurisdictions). Representative recent solicitations include Hillsborough County Water Resources Department's ITB-26-00138 for mercury float switches (two-year term, $60,000 estimated value, due March 2, 2026), and Hillsborough County's ITB-26-00123 for Square D contact kits (two-year term, $184,000 estimated value, due February 24, 2026)—both seeking UL-listed components for well and lift-station pump control. Eastern Municipal Water District's RFPAR3928 (due May 9, 2026) procured a single medium-voltage soft starter unit rated 2400V, 97A, 450HP with installation and training, reflecting the code's actual utility: electrical switchgear and control hardware for mission-critical water and facility systems rather than personal lockout devices.
