A fuse-switch uses a fuse-link or fuse carrier as part of its moving switching contact system.

## What it represents

A fuse-switch uses a fuse-link or fuse carrier as part of its moving switching contact system. The equipment designation must identify the actual assembly rather than treating every fused switch as mechanically identical.

## How to read it

- Read the manufacturer's construction and operating instructions to establish the switching mechanism.
- 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

- Identify assembly type
- Name compatible fuse links
- Show operating handle reference

## Important distinction

Fuse-switch describes the moving contact construction; a fused switch is a broader functional description.

## Facts

- Drawing role: Fused circuit
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HFU1FS, VFU1FS (Autodesk identifiers; not IEC symbol numbers)
- Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name.
