Electrical Symbols — Maintenance
Electrical maintenance - troubleshooting electrical circuit.Schematic drawings intended for maintenance may have the principal signal paths highlighted to assist in understanding the signal flow through the circuit. More complex devices have multi-page schematics and must rely on cross-reference symbols to show the flow of signals between the different sheets of the drawing.

Most of the electrical symbols can be changed in their appearance, styles and colors according to users' requirements. Electrical symbols are used to represent various electrical and electronic devices in a schematic diagram of an electrical or electronic circuit.
The following table lists some maintenance electrical symbols in our electrical diagram software.
| Symbol | Meaning | |
| Electrical Symbols — Maintenance | ||
![]() | Signal generator | |
![]() | Linear element | |
![]() | Relay contacts | |
![]() | Relay coil | |
![]() | Switch | |
![]() | Composite circuit | |
![]() | Amplifier | |
![]() | Signal code, normal | |
![]() | Signal code, secondary flow | |
![]() | Reference signal | |
![]() | Energize relay signal | |
![]() | Transmitter pulse | |
![]() | Test signal | |
![]() | Feedback | |
Circuit diagrams are used for the design (circuit design), construction (such as PCB layout), and maintenance of electrical and electronic equipment. The diagrams are a big help when workers try to find out why a circuit does not work correctly.
How to Create an Electrical Diagram Using Maintenance 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: Schematic of Circuit.
