Description

Technical Field

[0002] A potentiometer is a resistor element with three terminals and whose resistance value can be adjusted according to a certain law of change. A potentiometer is usually composed of a resistor body and a movable brush. When the brush moves along the resistor body, a resistance value or voltage that is related to the displacement is obtained at the output end. A potentiometer can be used as a three-terminal element or a two-terminal element. The latter can be regarded as a variable resistor. Since its function in the circuit is to obtain an output voltage that is related to the input voltage, it is called a potentiometer. Carbon sheets are important components in potentiometers. In the production process of potentiometers, punching tooling is required to realize the forming process of carbon sheets.
