## Symbol convention

Convention: IEC
Form: Engaged mechanical coupling
Autodesk IEC-60617 Symbol Preview — Mechanical coupling qualifiers; vendor family reference, not certified IEC geometry or database identifier.

This indication identifies engagement between the represented mechanical elements.

## What it represents

This indication identifies engagement between the represented mechanical elements. The represented elements share the documented motion-transmission relationship in the engaged state. That state says nothing by itself about supply energisation or electrical contact position.
Show the driving/driven device identities and connect the engagement state to its actual feedback if used. Alternate publisher graphical forms are retained within this one concept.

## How to read it

- Document the elements coupled and the applicable state condition.
- Different published graphical forms for the same engagement are kept in one concept record.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- Document the elements coupled and the applicable state condition.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

Different published graphical forms for the same engagement are kept in one concept record.

## Facts

- Reference scope: Specific public IEC-context family form
