  2. Multiway switching - Wikipedia

    en.wikipedia.org/wiki/Multiway_switching

    In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.

  3. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

    A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.

    In summer, ceiling fans and table/floor fans circulate air within a room for the purpose of reducing the perceived temperature by increasing evaporation of perspiration on the skin of the occupants. Because hot air rises, ceiling fans may be used to keep a room warmer in the winter by circulating the warm stratified air from the ceiling to the ...

    Distribution board designed for ordinary low voltage single phase premises, primarily domestic and light commercial wiring. 3-phase power distribution boards are usually known as distribution boards. Distribution board (DB) Panel that splits power from one main source into separate circuits, each with independent protection.

  8. Charlieplexing - Wikipedia

    en.wikipedia.org/wiki/Charlieplexing

    A Charlieplexed digital clock which controls 90 LEDs with 10 pins of a PIC 16C54 microcontroller.. Charlieplexing (also known as tristate multiplexing, reduced pin-count LED multiplexing, complementary LED drive and crossplexing) is a technique for accessing a large number of LEDs, switches, micro-capacitors or other I/O entities, using relatively few tri-state logic wires from a microcontroller.

  9. Lighting control system - Wikipedia

    en.wikipedia.org/wiki/Lighting_control_system

    What made this protocol more attractive, and able to compete with the established analog option, was the simple wiring. There are two types of lighting control systems which are: Analog lighting control; Digital lighting control; Examples for analog lighting control systems are: 0-10V based system.
