Right, Less mess? I have enough info in each of these diagrams to know precisely what this circuit will do and where to search for issues. Hope that this helps. ( Note: do not confuse circuit or schematic diagrams together with wiring diagrams; wiring diagrams will typically show pictures of components such as the pictorial, and also how the entire or part of a circuit will be wired. The distinction is that wiring diagrams usually put an emphasis on real physical location of necessary elements relative to each other that basically tell a layman Just What to do about the wiring. )
Think of it in this way; a circuit structure is any sort of diagram that illustrates the way the circuit operates where the major goal is the appropriate wiring of components and their relationship to each other rather than physical location relative to one another or intending prototypes. However, in some applications classifying diagrams can be hard so consider this as general information. I've found this is particularly true when working with more complex circuits and electronic equipment. I'm going to work with a more straightforward but average industrial circuit because these circuit set ups are exactly the same, but nevertheless where you can see how each type of diagram shows the role of the circuit in their own ways.
Here is another schematic diagram demonstrating the identical circuit, connections and components and it looks different but they both fall into precisely exactly the identical category.
Here's a technical version of a design diagram called a ladder structure. The main aim of this diagram is to demonstrate the logic (speaking to electric control) of a circuit board. This really is the one that I mostly come across in my line of work, and it's extremely successful for troubleshooting issues or learning how a circuit functions. Some circuits are so enormous that most kinds of schematic diagrams have to be read in increments in book form (generally with coded numbers so info can be simpler found). Again, here is the same precise circuit since the first two, but looking at it in ladder form.
A schematic diagram refers to a particular sort of circuit design that uses standard electrical/electronic symbols instead of images to demonstrate the way the circuit (or a part of it) works. Below is a typical 3-wire motor control circuit utilizing a standard momentary stop - start pushbutton channel using a schematic diagram. (Momentary here means that the button/switch you activate will go back to its default place once you physically let go of it, usually by a spring which forces the button/switch to get this done.)
Pictorial design diagrams, or pictorial circuit diagrams are essentially the exact same thing with exactly the identical purpose, but they use images of elements within the circuit instead of symbols. Again, here is the exact specific circuit (virtually except a control transformer was inserted and they are using conductors L1 and L3 instead of L1 and L2.
