Understand the difference.

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

LS FLOAT NC

IEEE / ANSI

ANSI/IEEE float level switch nc symbol

The float-operated NC form represents a normally continuous contact path influenced by liquid level. The level condition cannot be deduced from NC alone because the selected float arrangement establishes its operating direction.

Form evidence

Autodesk IEEE-oriented Miscellaneous 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

A closed reference contact does not automatically identify a low-level alarm.

LS FLOAT NC

Symbols

Float level switch NC

A float-operated NC level switch opens when its documented level condition actuates the mechanism. Reference state and level direction must be shown for alarm or pump-control interpretation.

A distinction that matters

NC does not necessarily mean low-level trip; the selected mechanism defines the process action.
