The black arc seen in the picture is a resistance track.
Above images shows the components of preset that are used to structure it.
Working of presets is quite simple. It works by having a resistive track and a small plate having dents to short the track. This small plate can be rotated using a screw driver or some similar tool. Position of the dents on the track determines the amount of resistance that is to be used in the circuit.
