Mini slide potentiometer      

Mini slide potentiometer, also known as "pots" or variable resistors, are usually manufactured to maintain their original characteristics no matter how long they are used. When position sensors are used, potentiometers can be linear or rotary position sensors. The potentiometer outputs a voltage value proportional to the position of the slider along the variable resistor. Because temperature change, abrasion and fouling between slider and variable resistor will cause resistance change and affect the accuracy of potentiometer, so the accuracy of potentiometer is too low. Due to the development of materials, especially conductive plastics, potentiometers can maintain their original characteristics after a long time of use, and improve their performance at the same time.
