Abstract
A potentiometer which is adapted to be produced fully automatically includes a spring support (2) formed in one piece by injection molding of plastic material and given such configuration that it embraces such functional members as the slider spring (3), resistor plate (5), and base plate (6). The casing (1), is also molded in the same working operation. The casing (1) and spring support (2) are interconnected by a sprue lug (7) which is removed by shearing.
