Rotary Potentiometer 3 Pin – Volume Control is a compact single-turn variable resistor for electronics projects requiring manual adjustment.

Rotary Potentiometer 3 Pin – Volume Control

A rotary potentiometer 3 pin is an adjustable component used in audio controls and electronic circuits. Turning its shaft moves an internal contact, allowing you to vary the output from a voltage-divider circuit. Depending on how it is connected, it can also provide adjustable resistance.

This potentiometer is useful for compatible amplifier volume controls, DIY audio projects, Arduino experiments, and other circuits that need a manual adjustment knob. Its three terminals connect to the ends of the resistive track and the adjustable centre contact, commonly called the wiper.

Key features

• Three terminals for adjustable circuit control
• Rotating shaft for manual adjustment
• Suitable for compatible audio volume-control projects
• Useful in DIY electronics, prototyping, and educational circuits

Before you order

Potentiometers are sold in different resistance values, tapers, shaft sizes, and mounting styles. Select the version required by your circuit. For an audio volume control, also check whether your design calls for an audio/logarithmic taper; a linear-taper potentiometer may behave differently when adjusting volume.

Order your rotary potentiometer from Mekatroniks in Pakistan for your next electronics or audio project.

Product-data note: Add the actual resistance value and taper to the product title and specifications once you confirm them—for example, 10kΩ linear or 100kΩ audio taper. The current copy avoids claiming a value or taper that has not been provided.

Key Features

• 3-pin rotary design
• Single-turn adjustment
• Compact PCB-friendly component
• Suitable for control circuits and DIY electronics

Applications

Commonly used for adjustable control functions such as audio volume and circuit parameter adjustment. Confirm the required resistance value and electrical rating for your circuit before ordering.
