Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

IEEE / ANSI

ANSI/IEEE Two-pole power switch form

This reference locates two-pole power switch in Autodesk's IEEE-oriented power switches family. 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. The public library uses HCB11Q50 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

A distinction that matters

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