# ANSI/IEEE Pull-cord switch form Canonical URL: https://eloragrid.ai/symbols/ansi-pull-cord-switch Publisher: Elora Grid Updated: 2026-10-28 Lookup label: PULL CORD Drawing use: Schematic Reference families: IEEE / ANSI, Manufacturer ## Symbol convention Convention: IEEE / ANSI Form: Pull Cord Switch, Normally Closed Autodesk IEEE Symbol Preview: Miscellaneous Switches, block HPC12. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier. Related representation: [Pull-cord switch](https://eloragrid.ai/symbols/pull-cord-switch) 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. ### This particular reference IEEE-library form of pull-cord switch: a pull-cord switch converts a cord-operated mechanical action into an electrical contact change. A generic pull-cord symbol does not certify an emergency-stop function. ### Terms - Normally open / normally closed: The contact state in the normal condition defined for the drawing. - Signal: Electrical information passed between devices, rather than necessarily the main power supply. - Rating: A value stating the conditions for which equipment is specified. Concept diagram: Identify the device and form → Read the connections and state → Check the equipment reference A guide to reading this reference.

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 ## Important distinction A generic pull-cord symbol does not certify an emergency-stop function. ## Facts - Convention evidence: Autodesk IEEE Symbol Preview: Miscellaneous Switches; published form: Pull Cord Switch, Normally Closed. - Public vendor block: HPC12. Vendor library token, not an IEEE symbol number. - Drawing role: Manual operation - Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name. - Artwork scope: Original educational geometry. Exact standard graphics, product ratings and terminal pinouts are not certified. ## Public references - [Autodesk IEEE Symbol Preview — Miscellaneous Switches](https://help.autodesk.com/cloudhelp/2021/ENU/AutoCAD-Electrical/files/GUID-278F6C21-B1A6-4EA1-A535-E78D53BBD10D.htm) — Autodesk. Public IEEE-oriented Miscellaneous Switches table explicitly lists HPC12 as Pull Cord Switch, Normally Closed.
