Electrical Symbols — Lamps, Acoustics, Readouts
Wiring and circuit diagrams use special symbols recognized by everyone who uses the drawings. The symbols on the drawings show how components like resistors, capacitors, inductors, switches, lamps, acoustic devices, measuring devices and other electrical and electronic components are connected together.

How to Create an Electrical Diagram Using Lamps Acoustics Readouts Library
- Open ConceptDraw DIAGRAM new document page.
- Select libraries from Electrical Engineering section.
-
There are a few different ways to place an object into your drawing:
- Click on an object and then click on the document, at the place you want the object to be inserted.
- Perform a drag-and-drop from the library to your document.
- Double click on an object’s icon in the library to place an object in the center of your document.
- Select the Smart Connector tool
. To connect elements using this tool, drag the connector from one connect dot to another.You can use Layers to place connections on different layers.
- Result: Electrical Diagram.

Fire Evacuation Plan Template →
Have you ever created the fire plans on the base of Fire Evacuation Plan Template? It's incredibly convenient and time-saving way. Let's try to make sure this with Fire and Emergency Plans solution for ConceptDraw DIAGRAM software.
Network VOIP. Computer and Network Examples →
Voice-over-Internet protocol (VoIP) is a protocol of the voice communications and multimedia sessions through the Internet or other packet-switched networks. VoIP systems use the data compression techniques, encapsulated in a data-packet stream over IP. They allows users to use regular telephone networks through any internet service provider and anywhere. VoIP is also called IP telephony, Internet telephony, Voice over broadband (VoBB). This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the VoIP Network.
Daisy Chain Network Topology →
This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park. A Daisy Chain is the simple computer network. It is the easiest way to add more Ethernet devices into the network. In the Daisy Chain network one computer is connected to the next without any intervening devices, thus the message is sent from one computer to the next and then to the next and so on. A Daisy Chain can be linear or ring
Electrical Symbols — Transistors →
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.
UML Class Diagram Notation →
When it comes to system construction, a class diagram is the most widely used diagram. UML Class Diagrams is a type of static structure diagram that is used for general conceptual modeling of the systematics of the application. Such a diagram would illustrate the object-oriented view of a system. The object orientation of a system is indicated by a class diagram. It describes the structure of a system by showing the general issues,classes of a system, attributes, operations, interfaces, inheritance, and the relationships between them.
