## Symbol convention

Convention: IEC
Form: Cam-operation qualifier
Autodesk IEC-60617 Symbol Preview — Operating-device and function qualifiers; vendor family reference, not certified IEC geometry or database identifier.

This qualifier identifies operation by a cam mechanism.

## What it represents

This qualifier identifies operation by a cam mechanism. A cam can operate contacts according to its mechanical position. The cam action explains the driving relationship while the contact table explains the electrical sequence.
Where several contacts share one cam-operated assembly, maintain the common device identity and list the states at each defined position. Do not infer that all contacts change at the same instant.

## How to read it

- Relate the cam position or sequence to the associated contact truth table.
- The cam qualifier alone does not show the full switching programme.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- Relate the cam position or sequence to the associated contact truth table.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

The cam qualifier alone does not show the full switching programme.
