A design diagram refers to a particular type of circuit design which uses standard electrical/electronic symbols rather than pictures to demonstrate the way the circuit (or portion of it) functions. Below is a normal 3-wire motor controller circuit using a typical momentary stop - start pushbutton station utilizing a schematic diagram. (Momentary this means that the button/switch you trigger will go back to its default position once you let go of this, typically by a spring that compels the button/switch to do this.)
Think of it in this way; a circuit structure is any sort of diagram which demonstrates the way the circuit operates where the major objective is the proper wiring of elements and their relationship to each other rather than physical location relative to one another or planning prototypes. Nonetheless, in some uses Assessing diagrams can be challenging so choose this as general advice. I have discovered this is particularly true when dealing with much more complicated circuits and electronics. I'm likely to work with a simpler but typical industrial circuit because these circuit setups are the exact same, but nevertheless where you're able to see how each sort of diagram shows the role of the circuit in their own manners.
Here is another schematic diagram demonstrating exactly the same circuit, components and connections and it looks different but they both fall into precisely exactly the identical category.
Right, much less clutter? I have enough information in each one these diagrams to know precisely what this circuit does and also where to search for issues. Hope that this helps. ( Note: don't confuse lecture or circuit diagrams together with wiring diagrams; wiring diagrams will usually show images of components like the pictorial, and the way the entire or part of a circuit is wired. The distinction is that wiring diagrams typically place an emphasis on real physical place of necessary elements relative to each other that basically tell a layman Just What to do concerning the wiring. )
Here is a version of a diagram known as a ladder design. The major aim of this diagram is to show the logic (speaking to electrical control) of a circuit. This diagram is the one I mainly encounter in my line of work, and it is extremely effective for troubleshooting problems or learning the way the circuit functions. Some circuits are so enormous that many types of schematic diagrams have to be read in increments in novel form (generally with coded numbers so that info can be simpler found). Again, here is the exact specific circuit as the first 2, however, considering it in ladder shape.
Pictorial schematic diagrams, or graphic circuit diagrams are basically the identical thing with the exact identical purpose, however they use images of components within the circuit instead of symbols. Again, here's the identical exact circuit (almost except a control transformer was inserted and they're using conductors L1 and L3 rather than L1 and L2.
