Potentiometer rotary switch is a common electrical component used to regulate voltage or current in circuits. It usually consists of a rotating axis and a set of contact points, which can change the position of the contact points through the rotation of the rotating axis, thereby achieving changes in resistance values or switching of switch states.

Main features:
1. Adjustment function: The potentiometer can adjust the resistance value by rotating, and is commonly used for volume control, brightness adjustment, and other applications.

2. Rotation method: Usually clockwise or counterclockwise rotation, some models may support infinite rotation.

3. Contact point: The internal structure usually includes a movable sliding contact point that slides along a fixed resistor and is connected to the fixed contact point.

4. Calibration: Many potentiometers are marked with scale lines so that users can intuitively understand the current setting value.

5. Type:
Linear potentiometer: The resistance value changes linearly.
Logarithmic potentiometer: The resistance value changes in logarithmic proportion and is commonly used in audio applications.

Application areas:
Audio equipment: Control the volume and quality of sound.
Lighting adjustment: Adjust the brightness of the lights.
Home appliances: such as fan speed adjustment, electric water heater temperature setting, etc.
Instrumentation: Used for precise control and measurement.

Precautions for use:
Voltage resistance: Ensure that the rated voltage of the potentiometer is higher than the voltage in actual application.
Power: Pay attention to the maximum power consumption of the potentiometer, overload may cause damage.
Wiring: Connect the wiring correctly to avoid short circuits or malfunction.

In short, potentiometer rotary switches play an important role in many electronic devices, achieving various functions through simple and effective rotation control.
