Established in 1922, TORK began manufacturing Electro-Mechanical Time Switches for the automatic control of lighting and electrical equipment. These products range from a simple ON/OFF at the same time everyday to different schedules each day of the week. For example, a neon store sign could turn on every day at 7:00 P.M. and off at midnight when diminished street traffic no longer warrants this advertising.

In 1989 TORK introduced a line of audible and visual signaling devices under the brand name TORK-Alert. These products, for commercial or industrial applications, include bells, horns, and warning lights.
