UNSPSC 39122213: Limit switch

UNSPSC 39122213 Limit switch (Commodity) covers specialized electrical switching components that state and local governments procure for infrastructure maintenance, system upgrades, and facility operations. Recent solicitations show the code capturing a range of electromechanical switching devices—from mercury float switches that control pump operations in water systems, to solenoid lock switches in transit equipment, to contact kits for motor control. The issuing bodies span water utilities, transit authorities, school districts, and county maintenance departments, with Hillsborough County Water Resources Department and Dallas Area Rapid Transit Authority appearing as repeat buyers of specific switch types. State and local governments buy these components on both project bases (network and facility upgrades) and as ongoing supplies for maintenance programs.

Geographic activity concentrates in Texas, Florida, and Georgia based on recent postings. Representative opportunities include Hillsborough County Water Resources Department's ITB-26-00138 for mercury float switches (due March 2, 2026) estimated at $60,000 over two years; Texas Department of Criminal Justice's solicitation IW248707 for electrical switches at the Woodman Unit (due April 29, 2026); and Dallas Area Rapid Transit Authority's multiple purchase orders for solenoid lock switches (Reference 2099242, due May 20, 2026) and traction power fuses, all requiring FOB Destination delivery and Net 30 payment terms. A Sourcewell cooperative procurement (RFP #061626) posted May 12, 2026, encompasses law enforcement equipment across multiple states and may include switching components. Evaluation criteria typically weight price heavily, with some procurements requiring brand-specific compliance (Square D, Schneider Electric, Meraki) or manufacturer equivalents and strict adherence to all line items for award eligibility.
