Thumbwheel Potentiometers

3352K-1-103 is a type of thumbwheel potentiometer that is widely used in the electronics and electrical appliances industry. Through the precise proportioning of the resistance value, 3352K-1-103 can be used in a variety of applications and scenarios. In this article, the application field and working principle of 3352K-1-103 are discussed.

Application Field

There are two major application fields for 3352K-1-103. First of all, they are commonly used in audio equipment, such as turntable platters and phono cartridges. The thumbwheel potentiometer is mounted on the platter of a turntable and adjusts the recorded signal strength of the various frequencies. Also, they are used in some types of lighting fixtures, such as halogen and LED light bulbs. In this application, the thumbwheel potentiometer is used to adjust the brightness of the bulb, up to a certain power level.

In addition, the 3352K-1-103 is also used in some measuring instruments such as digital meters, medical equipment, motor control systems, and consumer electronics. With its accurate control of resistance, the 3352K-1-103 can accurately measure current, voltage or other parameters and provide precise control signals to the motor control system.

Working Principle

The working principle of the 3352K-1-103 thumbwheel potentiometer is that the resistance is changed in proportion to the rotation of the thumbwheel. When the thumbwheel is rotated, the contact is moved along the resistance curve, increasing or decreasing the resistance value according to the symmetrical proportion of the resistance curve.

The resistance value of the 3352K-1-103 can be accurately adjusted by adjusting the knob or thumbwheel. In addition, the resistance remains constant during the life of the device, and there is no need for frequent adjustment. This is why thumbwheel potentiometers are widely used in audio, lighting and other applications.
