TORK began manufacturing Electromechanical Time Switches in the early 1920’s for the automatic control of lighting and electrical equipment. TORK shortly began producing photoelectric controls. TORK introduced its first digital controls in 1982. TORK’s digital units provide sophistication and versatility while promoting energy conservation in commercial and industrial buildings. Known as "the choice of professionals", TORK's spec grade energy controls have proved to be the #1 preference of Electrical Consultants.

In the past 20 years, TORK expanded electronic products to include occupancy sensors, audible and visual signaling devices under the brand name TORKALERT™ including bells, horns, and warning lights. Now, as a division of NSi Industries, TORK brings you Residential Timers, Air Conditioning Disconnects, Weatherproof Covers and Pool/Spa Controls; and continues to engineer top of the line spec grade products with the engineers, project managers and electricians in mind.
