A two-pole power switch operates two circuit conductors through a common device.

## What it represents

A two-pole power switch operates two circuit conductors through a common device. The schematic may use separate pole elements linked by a mechanism annotation.

## How to read it

- Identify whether the two poles are phases, a phase and neutral, or DC conductors.
- 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

- Name both conductors
- Show common operator
- Reference switching ratings

## Important distinction

Two poles do not necessarily mean a two-phase supply.

## Facts

- Drawing role: Switching path
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HCB11Q50, VCB11Q50 (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.
