Understand the difference.

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

HPB11LSL

IEEE / ANSI

ANSI/IEEE Latched lever-operated switch form

This reference locates latched lever-operated switch in Autodesk's IEEE-oriented miscellaneous switches family. This representation distinguishes a lever actuator with a maintained or latched operated state. The public library uses HPB11LSL for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

A distinction that matters

The lever mechanism and contact state remain separate aspects of the circuit.
