Understand the difference.

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

NO LATE

IEEE / ANSI

ANSI/IEEE late-make normally-open contact symbol

The delayed NO contact form identifies later operation in a documented contact sequence. The drafting reference must say which contacts or mechanism establish the sequence rather than interpreting geometric spacing as a time interval.

Form evidence

Autodesk IEEE-oriented Relays and Contacts 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 delayed sequence qualifier is not necessarily an independently adjustable timer function.

NO LATE

Symbols

Late-make normally-open contact

A late-make NO contact closes later in a documented mechanism sequence than associated contacts. The annotation must remain linked to the common device when contacts are drawn on different sheets.

A distinction that matters

Late make differs from an electrically timed on-delay contact.
