东莞电位器具有变阻的特征，接受噪声是电位器的电位器是在电阻器基础上发展起来的，所以电位器的选用参数包括了电阻器的一切参数。另外，电位器结构形式、功能特点又与电阻器不同，它的选用参数比电阻器多。下面介绍电位器的接触噪声。

Dongguan potentiometer has a variable resistance feature, acceptance of noise of the potentiometer resistor potentiometer is developed on the basis of the selection of parameters, so the potentiometer resistor parameters include all. In addition, the potentiometer structure, function characteristics and resistor is different, its selection parameters than resistors. Following the presentation of potential exposure to noise.
