UNSPSC 39122228: Vacuum switch

UNSPSC 39122228 Vacuum switch is a Commodity code covering specialized electrical switching components procured by state and local agencies primarily for infrastructure maintenance, transit operations, and facility upgrades. Recent solicitations show the code encompasses mercury float switches for water utility pump control, solenoid lock switches for transit rail systems, and network switch installation labor—a broader scope than the abstract code name suggests, with state and local buyers treating "switch" categories to include control-related electrical components and associated installation services rather than vacuum switches specifically.

State agencies, county utilities, transit authorities, and school districts dominate recent activity. The Dallas Area Rapid Transit Authority (DART) appears repeatedly across multiple February 2026 purchase orders for traction power fuses, power converters, and obstruction light assemblies, all posted with two- to four-day response windows on the BONFIRE platform. Hillsborough County Water Resources Department has posted two separate ITBs in January and February 2026 for mercury float switches and Square D contact kits totaling $244,000 over two years. School districts are also active: Bibb County Public Schools posted an RFP on January 30, 2026 for network switch installation across 45 locations with a March 2, 2026 deadline, and Northside Independent School District in San Antonio solicited electrical equipment and parts broadly on June 8, 2026 with a July 1, 2026 due date. The City of Dallas issued a sixty-month ID/IQ master agreement for electrical supplies in February 2026. Geographic concentration is heaviest in Florida (Hillsborough County, Orange County Transportation Authority) and Texas (DART, Dallas, Northside ISD, TDCJ), with secondary activity in Georgia (Gordon County Schools, Bibb County Schools) and Connecticut (City of Norwalk). Recent solicitations range from narrow commodity buys (mercury floats, specific contact kits) to broader as-needed electrical supply agreements, with response deadlines consistently tight (four to eight weeks) and most awards weighted heavily toward lowest price on firm, fixed pricing with delivery within 15 to 30 days required.
