Understand the difference.

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

SEL 4 HOLD

IEEE / ANSI

ANSI/IEEE four-position maintained selector symbol

The four-position maintained selector form supports four stable selections tied to a documented contact table. Position order matters when interpreting mode combinations, but physical rotation alone does not identify connected circuits.

Form evidence

Autodesk IEEE-oriented 4 Position Selector Switches functional form. Autodesk explicitly publishes this block under IEEE Symbol Preview. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.

A distinction that matters

Four stable positions do not necessarily mean four contact poles.

SEL 4 HOLD

Symbols

Four-position maintained selector

A four-position maintained selector provides four stable operating choices. Each contact's state across those choices is recorded in a schedule instead of trying to express the complete logic in one contact outline.

A distinction that matters

Four positions do not imply four independent contact poles.
