IEEE / ANSI

ANSI/IEEE Touch-switch NC output form

This reference locates touch-switch nc output in Autodesk's IEEE-oriented touch switches family. This form identifies a normally-closed touch-switch output. The public library uses HPX12TS 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 Sense Proximity Switch, Normally Closed. Autodesk IEEE Symbol Preview: Touch Switches, block HPX12TS. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier.

A distinction that matters

Normally closed touch output is not a mechanical NC pushbutton contact.
