2. Dimmer - Wikipedia

   en.wikipedia.org/wiki/Dimmer

   Since semiconductor or solid-state dimmers switch quickly between a low resistance "on" state and a high resistance "off" state, they dissipate very little power compared with the controlled load. Most recently, software programmable internal dimmers can use signals from the same switch that turns lights on and off to control dimming.

3. Wireless light switch - Wikipedia

   en.wikipedia.org/wiki/Wireless_light_switch

   Dimmer light switch with RF-based remote control [1] A wireless light switch is a light switch that commands a light or home appliance to turn itself off or on, instead of interrupting the power line going to the light fixture. There are different ways to communicate between the switch and the fixture: [2]

4. 0-10 V lighting control - Wikipedia

   en.wikipedia.org/wiki/0-10_V_lighting_control

   The switch is controlled by a PWM (Pulse Width Modulation) signal, which alternately turns the switch on and off at a rapid rate. The relative proportion of off time vs. on time determines brightness. For example, if the switch is off 10% of the time, the resulting control signal would be the equivalent of 1 V produced with a variable resistor.

5. Light switch - Wikipedia

   en.wikipedia.org/wiki/Light_switch

   Manually operated on/off switches may be substituted by dimmer switches that allow controlling the brightness of lamps as well as turning them on or off, time-controlled switches, occupancy-sensing switches, and remotely controlled switches and dimmers. Light switches are also found in flashlights, vehicles, and other devices.

   A simple on-off switch: The two terminals are either connected together or disconnected from each other. An example is a light switch. SPST-NO. Form A [4] Single pole, single throw, normally open A simple on-off switch. The two terminals are normally disconnected (open) and are closed when the switch is activated. An example is a pushbutton ...

7. Lighting control console - Wikipedia

   en.wikipedia.org/wiki/Lighting_control_console

   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 ...
