"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 most familiar form of switch is a manually operated electromechanical device with one or more sets of electrical contacts, which are connected to external circuits. Each set of contacts can be in one of two states: either "closed" meaning the contacts are touching and electricity can flow between them, or "open", meaning the contacts are separated and the switch is nonconducting. The mechanism actuating the transition between these two states (open or closed) can be either a "toggle" (flip switch for continuous "on" or "off") or "momentary" (push-for "on" or push-for "off") type.
A switch may be directly manipulated by a human as a control signal to a system, such as a computer keyboard button, or to control power flow in a circuit, such as a light switch. Automatically operated switches can be used to control the motions of machines, for example, to indicate that a garage door has reached its full open position or that a machine tool is in a position to accept another workpiece. Switches may be operated by process variables such as pressure, temperature, flow, current, voltage, and force, acting as sensors in a process and used to automatically control a system. ... A switch that is operated by another electrical circuit is called a relay. Large switches may be remotely operated by a motor drive mechanism. Some switches are used to isolate electric power from a system, providing a visible point of isolation that can be padlocked if necessary to prevent accidental operation of a machine during maintenance, or to prevent electric shock." [Switch. Wikipedia]
"A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal. The first relays were used in long distance telegraph circuits as amplifiers: they repeated the signal coming in from one circuit and re-transmitted it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations.
A type of relay that can handle the high power required to directly control an electric motor or other loads is called a contactor. Solid-state relays control power circuits with no moving parts, instead using a semiconductor device to perform switching. Relays with calibrated operating characteristics and sometimes multiple operating coils are used to protect electrical circuits from overload or faults; in modern electric power systems these functions are performed by digital instruments still called "protective relays"."

Network Layout

The Network Layout Diagram visually illustrates the arrangement of computers, nodes and other network appliances, such as servers, printers, routers, switches, hubs, and their relationships between each other. The network layout and placement of servers greatly influence on the network security and network performance. Elaboration of robust Network Layout Diagram is especially important when visualizing already existing network in order to understand its complexity; when troubleshooting the network issues; designing, documenting and implementing new network configurations; extending, modifying, or moving an existing network to other location. Through the careful thinking the network plan and designing the clear Network Layout Diagram, you can be confident in result on the stage of network implementation and to solve faster the problems appearing in network infrastructure. ConceptDraw DIAGRAM enhanced with Computer Network Diagrams solution from Computer and Networks area perfectly suits for drawing Network Layout Diagrams for different network topologies.

ConceptDraw Arrows10 Technology

You can see that when you rotate a group, connectors change their angle, keeping their position inside of the grouped objects. If you decide to ungroup the objects, the connectors will adjust to keep lines parallel to the edges of the sheet. The magic of ConceptDraw Arrows10’s rotating group containing connectors, makes complex diagramming simple and easy. The way to connect objects has never been easier.

Use it for drawing HVAC system diagrams, heating, ventilation, air conditioning, refrigeration, automated building control, and environmental control design floor
plans and equipment layouts.
"HVAC (... Heating, Ventilation and Air Conditioning) is a control system that applies regulation to a heating and/ or air conditioning system. ...
Central controllers and most terminal unit controllers are programmable, meaning the direct digital control program code may be customized for the intended use. The program features include time schedules, setpoints, controllers, logic, timers, trend logs, and alarms. The unit controllers typically have analog and digital inputs that allow measurement of the variable (temperature, humidity, or pressure) and analog and digital outputs for control of the transport medium (hot/ cold water and/ or steam). Digital inputs are typically (dry) contacts from a control device, and analog inputs are typically a voltage or current measurement from a variable (temperature, humidity, velocity, or pressure) sensing device. Digital outputs are typically relay contacts used to start and stop equipment, and analog outputs are typically voltage or current signals to control the movement of the medium (air/ water/ steam) control devices such as valves, dampers, and motors."
