# ANSI/IEEE Latched foot-operated switch form Canonical URL: https://eloragrid.ai/symbols/ansi-latched-foot-operated-switch Publisher: Elora Grid Updated: 2026-10-28 Lookup label: HFT11L Drawing use: Schematic Reference families: IEEE / ANSI, Manufacturer ## Symbol convention Convention: IEEE / ANSI Form: Pedal Switch Latched, Normally Open Autodesk IEEE Symbol Preview: Miscellaneous Switches, block HFT11L. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier. Related representation: [Latched foot-operated switch](https://eloragrid.ai/symbols/iec-latched-foot-operated-switch) IEEE-library form of latched foot-operated switch: this representation distinguishes a foot actuator with a retained operated state. ## In plain English ### What does ANSI/IEEE Latched foot-operated switch form mean? This reference locates latched foot-operated switch in Autodesk's IEEE-oriented miscellaneous switches family. This representation distinguishes a foot operating mechanism with a retained operated state. The public library uses HFT11L 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 Show reset/release behaviour and the associated contact conditions. A latched pedal should not be read as a momentary foot switch. Show reset/release behaviour and the associated contact conditions. A latched pedal should not be read as a momentary foot switch. 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 foot-operated switch: this representation distinguishes a foot operating mechanism with a retained operated state. A latched pedal should not be read as a momentary foot switch. ### 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.
