Side-by-side reference

Understand the difference.

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

HVR1R5

IEEE / ANSI

ANSI/IEEE Resistor with disconnecting slider form

This reference locates resistor with disconnecting slider in Autodesk's IEEE-oriented resistive components family. This form distinguishes a movable resistor contact with a disconnecting position. The movable contact can leave the resistive track at its documented disconnecting position. This changes circuit continuity as well as the selected resistance. The public library uses HVR1R5 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

A distinction that matters

A disconnecting slider is different from a continuously connected potentiometer wiper.
