The infinite switch itself was described in a 1975 patent of George F. Esker Jr. and Otto J. Cousins of the Harper Wyman Company. This switch would reset itself as the bi-metallic strip cooled, provided a cycle of calibrated opening and closing. It also provided an indicator light that remained on as long as the knob was not in the closed position.
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.

Many memory consoles have a bank of faders. These faders can be programmed to control a single channel (a channel is a lighting designer's numerical name for a dimmer or group of dimmers) or a group of channels (known as a ""submaster""). The console may also have provision to operate in analog to a manual desk for programming scenes or live ...

President Donald Trump assigned Sylvester Stallone, Mel Gibson, and Jon Voight as special "envoys" to Hollywood, prompting experts to speculate on the exact nature of their roles in the industry.
Adjusting the brightness of light emitted by a light source is then merely a matter of setting at what voltage (or phase) in the AC half-cycle the dimmer begins to provide electric current to the light source (e.g. by using an electronic switch such as a triac). In this case the PWM duty cycle is the ratio of the conduction time to the duration ...
