Drawing use: Schematic
Reference families: IEC, Manufacturer

## Symbol convention

Convention: IEC
Form: Mechanical stop latch in neutral state
Autodesk IEC-60617 Symbol Preview — Mechanical return and interlock qualifiers; vendor family reference, not certified IEC geometry or database identifier.

This form identifies the neutral state of the represented stop-latch mechanism.

## What it represents

This form identifies the neutral state of the represented stop-latch mechanism. Neutral describes the represented retaining mechanism, not every electrical contact belonging to the assembly. A state table provides the relationship between latch condition and contact states.
Identify the associated mechanism and define the neutral condition in its operating sequence. Use separate contact and position references when those interfaces appear elsewhere in the schematic.

## How to read it

- Keep neutral and engaged states explicit in state or sequence documentation.
- Neutral is a mechanism state, not an assertion that every contact is open.

## Information to show or reference

- Identify the associated device, circuit or diagram boundary.
- Keep neutral and engaged states explicit in state or sequence documentation.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

## Important distinction

Neutral is a mechanism state, not an assertion that every contact is open.
