Electrical Symbols — Switches and Relays
In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high-voltage circuits in electrical substations.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.
Example of DFD for Online Store (Data Flow Diagram)
Data flow diagrams (DFDs) reveal relationships among and between the various components in a program or system. DFDs are an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations.Example of DFD for Online Store shows the Data Flow Diagram for online store and interactions between the Visitors, Customers and Sellers, as well as Website Information and User databases.

Communication 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 communication network topology is defined by the evaluating costs of the states. Each state represents the possible distribution of the hubs and remote nodes to nodes of the communication network.
Time - Design Elements
Many of us want to be able to create designs efficiently yet quickly. ConceptDraw DIAGRAM will help you to make awesome drawings without having to design all those Time Elements. These elements include graphs, symbols, cliparts, visual data representation and a whole lot of other stuff.The design elements library "Cable TV" contains 64 symbols of CATV network equipment.
"Cable television is a system of distributing television programs to subscribers via radio frequency (RF) signals transmitted through coaxial cables or light pulses through fiber-optic cables. This contrasts with traditional broadcast television (terrestrial television) in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television. FM radio programming, high-speed Internet, telephone service, and similar non-television services may also be provided through these cables.
The abbreviation CATV is often used for cable television." [Cable television. Wikipedia]
Use the shapes library "Cable TV" to draw CATV system design floor plans, network topology diagrams, wiring diagrams and cabling layout schemes using the ConceptDraw PRO diagramming and vector drawing software.
The vector stencils library "Cable TV" is included in the Electric and Telecom Plans solution from the Building Plans area of ConceptDraw Solution Park.
