UNSPSC 39122225: Mercury switch

UNSPSC 39122225 Mercury switch is a Commodity code covering switching devices and components used in industrial, utility, and facility control systems. State and local governments procure mercury float switches, solenoid switches, electrical contact kits, and related switching equipment for water systems, transit infrastructure, correctional facilities, airport operations, school districts, and municipal utilities.
