# ANSI/IEEE Touch-sensitive switch form Canonical URL: https://eloragrid.ai/symbols/ansi-touch-sensitive-switch Publisher: Elora Grid Updated: 2026-10-28 Lookup label: HPX1TS Drawing use: Schematic Reference families: IEEE / ANSI, Manufacturer ## Symbol convention Convention: IEEE / ANSI Form: Touch Autodesk IEEE Symbol Preview: Touch Switches, block HPX1TS. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier. Related representation: [Touch-sensitive switch](https://eloragrid.ai/symbols/iec-touch-sensitive-switch) IEEE-library form of touch-sensitive switch: a touch-switch representation identifies operation by the documented touch-sensing mechanism. ## In plain English ### What does ANSI/IEEE Touch-sensitive switch form mean? This reference locates touch-sensitive switch in Autodesk's IEEE-oriented touch switches family. A touch-switch representation identifies operation by the documented touch-sensing mechanism. The public library uses HPX1TS 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 sensing role and separate power/output interfaces. Touch operation is distinct from a mechanical pushbutton mechanism. State the sensing role and separate power/output interfaces. Touch operation is distinct from a mechanical pushbutton mechanism. 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 touch-sensitive switch: a touch-switch representation identifies operation by the documented touch-sensing mechanism. Touch operation is distinct from a mechanical pushbutton mechanism. ### 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.
