IEEE / ANSI

ANSI/IEEE Touch-sensitive switch form

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.

Drawing use: Schematic
Application: Control circuits
Reference family: IEEE / ANSI / Manufacturer
Form evidence: 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.

A distinction that matters

Touch operation is distinct from a mechanical pushbutton mechanism.
