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
A distinction that matters
Two poles do not necessarily mean a two-phase supply.
