A time switch (also called a timer switch, or simply timer) is a device that operates an electric switch controlled by a timer. Intermatic introduced its first time switch in 1945, which was used for "electric signs, store window lighting, apartment hall lights, stokers, and oil and gas burners." A consumer version was added in 1952.
DIN rail mounted electronic lighting timer. An electronic timer allow simple push-buttons to be used. One timer is installed controlling the lights and any number of push-buttons, without pneumatic timers and connected in parallel, are used to trigger it. [1] [4] With many push-buttons, the cost savings for equipment may be substantial.
[1] By 1893, New York City had 1,535 electric arc street lights. [1] In New Orleans, arc lamps were used for street lighting starting in 1881. In 1882, the New Orleans Brush Lighting Company installed one hundred 2,000-candlepower arc lamps along five miles of wharf and riverfront; by 1885, New Orleans had 655 arc lights. [1]
Electromechanical timers survive in these applications because mechanical switch contacts may still be less expensive than the semiconductor devices needed to control powerful lights, motors and heaters. In the past, these electromechanical timers were often combined with electrical relays to create electro-mechanical controllers ...
In 2011, Lowe's ended its arrangement with Danaher and switched to a different supplier for its mechanic's hand tools, [5] JS Products of Las Vegas, Nevada. [6] Screwdrivers continue to be supplied by Great Neck. [7] The same year, the Kobalt line expanded to include cordless power tools, [8] manufactured by Chervon. [9]
Aside from movable parts, electrical relays are also used. In general, electro-mechanical signal controllers use dial timers that have fixed, signalized intersection time plans. Cycle lengths of signalized intersections are determined by small gears that are located within dial timers.
