  2. Relay - Wikipedia

    en.wikipedia.org/wiki/Relay

    Circuit symbols of relays (C denotes the common terminal in SPDT and DPDT types.) Since relays are switches, the terminology applied to switches is also applied to relays; a relay switches one or more poles, each of whose contacts can be thrown by energizing the coil. Normally open (NO) contacts connect the circuit when the relay is activated ...

  3. H-bridge - Wikipedia

    en.wikipedia.org/wiki/H-bridge

    A "double pole double throw" (DPDT) relay can generally achieve the same electrical functionality as an H-bridge (considering the usual function of the device). However a semiconductor-based H-bridge would be preferable to the relay where a smaller physical size, high speed switching, or low driving voltage (or low driving power) is needed, or ...

    This circuit diagram was created with Inkscape. This SVG circuit diagram shows a very simple image. Drawing uncomplicated graphics with a text editor seems more adequate than using a vector graphics program, and will often result in a dramatic reduction of file size.

  5. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering ...

  6. Multiway switching - Wikipedia

    en.wikipedia.org/wiki/Multiway_switching

    Systems based on relays with low-voltage control circuits permit switching the power to lighting loads from an arbitrary number of locations. For each load, a latching relay is used that mechanically maintains its on- or off-state, even if power to the building is interrupted. Mains power is wired through the relay to the load.

  9. Relay logic - Wikipedia

    en.wikipedia.org/wiki/Relay_logic

    The schematic diagrams for relay logic circuits are often called line diagrams, because the inputs and outputs are essentially drawn in a series of lines. A relay logic circuit is an electrical network consisting of lines, or rungs, in which each line or rung must have continuity to enable the output device. A typical circuit consists of a ...
