A latched key-operated switch retains its commanded position according to the selected mechanism.

## What it represents

A latched key-operated switch retains its commanded position according to the selected mechanism. The drawing should specify how the latched position is released and where the key is removable.

## How to read it

- Separate the mechanical retention from any electrical seal-in circuit.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.

## Information to show or reference

- List stable positions
- Show reset action
- Document key-removal constraints

## Important distinction

Mechanically latched operation is different from a relay holding circuit.

## Facts

- Drawing role: Manual operation
- Representation scope: Functional concept; not an official standard graphic or a product footprint
