Which details are not contained in a generic symbol?

Exact ratings, manufacturer catalog number, terminals, physical dimensions, environmental limits and installation instructions belong in the device or component record.

Can I use these symbols in an editable diagram?

Yes. Open any individual symbol reference, inspect its pins and meaning, then place it in the browser editor.

Which standard form should I use?

Use the convention required by the project, customer and jurisdiction. A page states an IEC or ANSI form only where the underlying reference data defines one.

Relay Symbols and Contact Reference

Quick answer: Relay drawings separate the operating coil from one or more controlled contacts. Coil and contact tags must make their relationship explicit, while the normal state is shown with the coil de-energized unless the drawing states otherwise.

Normal state is defined
Coil and contacts share a traceable tag
Terminal numbers match the selected relay
Coil voltage and suppression are documented

Symbol versus physical device

The symbol defines electrical intent. Use the linked component catalogue or a project-owned part record for dimensions, mounting, ratings, terminal mapping and manufacturer data.

Open the symbol library in the editor or browse the physical component catalogue.
