ANSI/IEEE Pull-cord switch form
IEEE-library form of pull-cord switch: a pull-cord switch converts a cord-operated mechanical action into an electrical contact change.
In plain English
What does ANSI/IEEE Pull-cord switch form mean?
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 operating mechanism placement. The public library uses HPC12 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.
A simple example
Read the operating mechanism and the contact reference state together. Cross-reference every associated contact to the same device and show which movement, signal or reset changes its condition; the symbol alone does not establish the complete switching sequence.
What the drawings help you do
State the normal condition and how operation is reset. A generic pull-cord symbol does not certify an emergency-stop function. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

How to read it
- State the normal condition and how operation is reset.
- 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
- Identify contact action
- Reference cord arrangement
- Show reset mechanism
A distinction that matters
A generic pull-cord symbol does not certify an emergency-stop function.
