Switch-position function qualifier

What it represents

This qualifier marks the publisher's switch-position function element. A position-function element contributes to the meaning of a compound switching representation. It is interpreted with the device boundary and contacts, not as a free-standing circuit element.

Preserve position labels and normal-state conventions when the compound symbol is expanded into several schematic contacts. Device tagging ties those views together.

How to read it

• Read position and switching action with the complete device symbol.
• A function qualifier is an element of a compound symbol rather than a complete device record.

Information to show or reference

• Identify the associated device, circuit or diagram boundary.
• Read position and switching action with the complete device symbol.
• Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
