Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

IEEE / ANSI

ANSI/IEEE Semiconductor power switch form

This reference locates semiconductor power switch in Autodesk's IEEE-oriented power switches family. A semiconductor power switch controls a power path electronically. Its power terminals and control input belong to different circuits, and off-state leakage or isolation characteristics require product documentation. The public library uses HCB11Q53 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

1P with Semiconductors. Autodesk IEEE Symbol Preview: Power Switches, block HCB11Q53. Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier.

A distinction that matters

A solid-state switch is not an isolating disconnector.
