# ANSI/IEEE Latched pull-cord switch form Canonical URL: https://eloragrid.ai/symbols/ansi-latched-pull-cord-switch Publisher: Elora Grid Updated: 2026-10-28 Lookup label: HPC11L Drawing use: Schematic Reference families: IEEE / ANSI, Manufacturer ## Symbol convention Convention: IEEE / ANSI Form: Pull Cord Switch Latched, Normally Open Autodesk IEEE Symbol Preview: Miscellaneous Switches, block HPC11L. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier. Related representation: [Latched pull-cord switch](https://eloragrid.ai/symbols/iec-latched-pull-cord-switch) IEEE-library form of latched pull-cord switch: this representation distinguishes a pull-cord actuator whose operated state is latched. ## In plain English ### What does ANSI/IEEE Latched pull-cord switch form mean? This reference locates latched pull-cord switch in Autodesk's IEEE-oriented miscellaneous switches family. This representation distinguishes a pull-cord operating mechanism whose operated state is latched. The public library uses HPC11L 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 Document the release/reset action and the normally open or normally closed contacts actually fitted. Latching behaviour differs from the pull-cord operation method alone. Document the release/reset action and the normally open or normally closed contacts actually fitted. Latching behaviour differs from the pull-cord operation method alone. 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 latched pull-cord switch: this representation distinguishes a pull-cord operating mechanism whose operated state is latched. Latching behaviour differs from the pull-cord operation method alone. ### 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 public library uses HPC11L for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number. 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. Document the release/reset action and the NO or NC contacts actually fitted. Latching behaviour differs from the pull-cord actuation method alone. Document the release/reset action and the NO or NC contacts actually fitted. Latching behaviour differs from the pull-cord actuation method alone. 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 - Document the release/reset action and the NO or NC contacts actually fitted. - Latching behaviour differs from the pull-cord actuation method alone. ## Information to show or reference - Identify the associated device, circuit or diagram boundary. - Document the release/reset action and the NO or NC contacts actually fitted. - Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form. ## Important distinction Latching behaviour differs from the pull-cord actuation method alone. ## Facts - Convention evidence: Autodesk IEEE Symbol Preview: Miscellaneous Switches; published form: Pull Cord Switch Latched, Normally Open. - Public vendor block: HPC11L.
