Thumbwheel potentiometers, such as the 3352K-1-202, are electromechanical devices that convert manual input through a rotating shaft into an output in the form of a resistance. They are used to adjust the resistance values of various circuits in a wide array of applications. The 3352K-1-202 is an adjustable, double-ended, parallel-shaft potentiometer that is specifically designed for use in telephone switchboards.

The 3352K-1-202 has a 100Ω resistance and is housed in an enclosure with two separate shafts. The shafts are each equipped with a set of thumbwheels that can be used to adjust the resistance. The top thumbwheel is used for coarse adjustment, while the bottom thumbwheel is used for fine adjustment. The thumbwheels are connected to a sliding contact, which is connected to the two resistive arms. As the thumbwheels are turned, the contact shifts along the resistive arms, increasing or decreasing the resistance accordingly.

The 3352K-1-202 is a versatile component and is used in a wide variety of applications. It is commonly used in telecommunications and electrical equipment, such as telephone switchboards, radio equipment, and test equipment. It is also used to adjust the resistance of feedback loops in power amplifiers, adjust the gain in signal-level circuits, and provide adjustable voltage dividers in power supply circuits. Additionally, it can be used to provide adjustable gains in RF amplifiers, adjustable outputs in instrumentation loops, and adjustable input impedances in oscillators.

The 3352K-1-202 is a reliable and efficient device that provides adjustable resistance in a variety of applications. Its adjustable thumbwheels and sliding contact make it easy to adjust resistance quickly and accurately. Additionally, its small size makes it ideal for space-constrained applications. The 3352K-1-202 is an affordable and versatile component that is suitable for a wide variety of applications.
