Understand the difference.

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

PULL CORD

IEEE / ANSI

ANSI/IEEE Pull-cord switch form

This reference locates pull-cord switch in Autodesk's IEEE-oriented miscellaneous switches family. A pull-cord switch converts a cord-operated mechanical action into an electrical contact change. The control drawing records the contact function, while the layout records the cord route and actuator placement. The public library uses HPC12 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

A distinction that matters

A generic pull-cord symbol does not certify an emergency-stop function.
