IEC

Resistor with disconnecting slider

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.

Drawing use: Schematic
Application: Electronic components
Reference family: IEC / Manufacturer
Form evidence: Resistor with disconnecting slider. Autodesk IEC-60617 Symbol Preview — Resistive component forms; vendor family reference, not certified IEC geometry or database identifier.

A distinction that matters

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

Resistor

A resistor representation identifies a resistive component in a circuit. Different drawing conventions can use different basic outlines, while additional qualifiers distinguish variable resistors, shunts or heating elements. The value, rating and purpose are separate annotations.

Drawing use: Schematic
Application: Control circuits
Reference family: IEC / IEEE / ANSI

A distinction that matters

IEC-style rectangular and other conventional resistor depictions can describe the same component concept, but qualifiers and documentation still matter.
