Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier. Related representation: [Resistor with disconnecting slider](https://eloragrid.ai/symbols/iec-resistor-with-disconnecting-slider) IEEE-library form of resistor with disconnecting slider: this form distinguishes a movable resistor contact with a disconnecting position. ## In plain English ### What does ANSI/IEEE Resistor with disconnecting slider form mean? 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 simple example Follow the actual current path and terminal polarity in the surrounding circuit. The symbol identifies an electrical function; voltage, current, energy limits and the device package pinout come from the selected component data rather than from the outline. ### What the drawings help you do Show the track ends, slider terminal and the off-position relationship. A generic potentiometer or variable-resistor graphic can omit this important additional operating state. Show the track terminals, movable contact and the circuit condition at the off position. A disconnecting slider is different from a continuously connected potentiometer wiper. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted. ### This particular reference IEEE-library form of resistor with disconnecting slider: this form distinguishes a movable resistor contact with a disconnecting position. A disconnecting slider is different from a continuously connected potentiometer wiper. ### Terms - Normally open / normally closed: The contact state in the normal condition defined for the drawing. - Terminal: An identified point where a conductor connects. - Rating: A value stating the conditions for which equipment is specified.
