Product introduction
Carbon film potentiometers, like ordinary potentiometers, have three pins. However, two metal static plates of different lengths are connected to two of the pins, and a metal movable plate with teeth is connected to the third pin.
There are four states when the carbon film potentiometer rotates; The carbon film potentiometer is made by coating a layer of carbon film on a horseshoe shaped paper rubber plate. The relationship between the resistance change of the carbon film potentiometer and the position of the intermediate contact is exponential
Linear and logarithmic. Carbon film potentiometers are divided into three types: micro, small and large. Some form potentiometers with switches together with switches.
