## Symbol convention

Convention: IEC
Form: Key-controlled two-way latching device
Autodesk IEC-60617 Symbol Preview — Latching-device qualifiers; vendor family reference, not certified IEC geometry or database identifier.

This form identifies a two-way latch using a documented key operation.

## What it represents

This form identifies a two-way latch using a documented key operation. A key controls the movement or release of the two-way latching arrangement. Its role is mechanical access/operation, while the associated electrical circuit retains its own contact logic.
Keep key identifiers and device tags consistent with the interlocking schedule. A single keyed-latch graphic cannot describe all exchanges in a multi-key sequence.

## How to read it

- Cross-reference the key arrangement and retained mechanism positions.
- A keyed latch does not establish a complete trapped-key sequence by itself.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- Cross-reference the key arrangement and retained mechanism positions.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

A keyed latch does not establish a complete trapped-key sequence by itself.
