This is particularly true when the resistor is used to control volume levels. Includes Dust Seal. A potentiometer consists of four main components: two fixed terminals, one moving terminal (called the wiper), a resistive strip or track, and the housing. In order to use the potentiometer as a rheostat or variable resistor, it should have only two terminals with one end and the wiper. The three main applications of a potentiometer are: 1. In its simplest configuration, a potentiometer may be used as a rheostat by simply using the wiper terminal and one of the other terminals, the third terminal left unconnected and unused: Moving the potentiometer control in the direction that brings the wiper closest to the other used terminal results in a lower resistance.

Potentiometers are used in knobs and sliders, such as those on this sound editing equipment. It converts rotary or linear motion from the operator into a change of resistance, and this change is (or can be) used to control anything from the volume of a hi-fi system to the direction of a huge container ship. Carbon rotary potentiometers are designed to be mounted onto the front panel of a case, enclosure or printed circuit board (PCB) using a ring nut and locking washer. Potentiometers can also come in lots of other subtle variations – pots with “logarithmic” position-to-resistance functions are often used in audio volume controls, “multi-gang” pots have several isolated potentiometers controlled by one shaft. In construction, a potentiometer uses either a two or three terminal configuration. It can also use as a variable resistor in most of applications. One of the outer pins is connected to the GND, the other to Vcc and the middle pin is the voltage output. Following are the terms used to describe types of potentiometers: Slider pot or slide pot: This can be adjusted by sliding the wiper right or left with a finger or thumb.
