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.
Lighting control devices and systems must be functionally tested (this includes occupancy sensors, time switches, programmable schedule controls and photosensors) [20] Advanced lighting control is an effort made by ASHRAE 90.1-2010 to significantly reduce the energy used for lighting by commercial buildings.

From permanent structures to portable options, there's a plant-nurturing solution for everyone.
The company introduced its first lighting timer in 1945, and today makes timing and control systems for line and low voltage systems used in residential, commercial, government, and industrial systems. [5] The company sells the Time-All line of timers for consumer applications. [6] [7]
A common dual dimmer module used in stage lighting A dimmer. A dimmer is a device connected to a light fixture and used to lower the brightness of the light.By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output.
According to the U.S. Energy Information Administration (EIA), "Electricity prices generally reflect the cost to build, finance, maintain, and operate power plants and the electricity grid." Where pricing forecasting is the method by which a generator, a utility company, or a large industrial consumer can predict the wholesale prices of ...
Energy conservation can be achieved through efficient energy use, which has some advantages, including a reduction in greenhouse gas emissions and a smaller carbon footprint, as well as cost, water, and energy savings. Green engineering practices improve the life cycle of the components of machines which convert energy from one form into another.
