Abstract
A movable electrical contact assembly forms a potentiometer and includes at least one strip of electrically conductive material having a significant resistance, a conductive rolling contact device in contact with the strip, a mechanism for moving the rolling contact device along the strip, and the rolling contact device or the strip being made of a deformable conductive material. In one preferred embodiment, two strips are provided at least one of which has a significant resistance. Also in one embodiment, the rolling contact device is deformable and is defined by a conductive elastomeric contact roller.
