Late-make normally-open contact
A late-make NO contact closes later in a documented mechanism sequence than associated contacts.

What it represents
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.
How to read it
- Establish the sequence from the device documentation rather than from symbol placement.
- 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
- Match common device tag
- Identify late closing transition
- Reference mechanism sequence
A distinction that matters
Late make differs from an electrically timed on-delay contact.
