Description

Technical Field

[0001] The invention relates to the field of potentiometers, in particular to a novel potentiometer. Background Art

[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 in a certain relationship with the displacement is obtained at the output end. The 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 in a certain relationship with the input voltage (applied voltage), it is called a potentiometer. However, in the prior art, the potentiometer requires a long assembly time and has many structural assembly components, which is not convenient for automated production.
