Plated precision potentiometer

A Plated Precision Potentiometer (PPP) comprising:

• a housing with a cylindrical opening within the walls of which are placed, parallel to the axis of the cylindrical opening, 6 rectangular plates made out of resistance material, a disc inside said housing through the center of which is a screw, as the screw rotates the disc moves along it and along the axis of the cylindrical opening, the diameter of the disc is equal to the diameter of the cylindrical opening, on one side of the disc is a contact ring which has the radius equal to the radius of the disc and the radius of the opening within the body of PPP, the movement of the disc along the axis of PPP is restricted by lids on both sides of the housing of cylindrical housing, the screw is attached to the lids in the cylinder and goes through the center of the disc, which does not allow the cylinder to rotate around the axis of the cylinder when the screw is rotating, springs are between the disc and the lids of the cylinder which guarantees the movement of the disc along the axis of the cylinder without a free movement when the direction of the movement of the disc is changed, the contact ring is made from an electrically conductive material, which is on one side of the disc, and cut into three equal parts or segments, which guarantee a paired electrical contact of the resistor plates, all points of contact of the segments and the resistor plates will always be in the same plain and perpendicular to the axis of the cylinder, 4 legs are along the body of the housing, and serve as a connection mechanism of the PPP to any circuit and two of said legs are used to connect the PPP to an electrical schematic, wherein the movement of the disc from one end of the PPP to the other causes the electrical resistance to be proportional to a change from 0 to Rmax, or from Rmax to 0 from the reversed movement of the disc, and the electrical resistance output has a linear characteristic.
