ABSTRACT:
The potentiometer consists of two halves. Each half has a base plate (5,6) ending in soldering lugs (51,61,62). One part each of a casing (1 or 2) and a rotary driver half (3 or 4, respectively) are molded to each base plate in a plastics injection molding process. The two potentiometer halves are interconnected at their casing parts (1,2), on the one hand, and at their rotary driver halves (3,4), on the other hand, by ultrasonic welding. For this purpose a circumferential thickening (15,47) each is provided of tapering shape. A slider spring (8) on the one hand has slider lobes (81) which slide on a resistor path of a resistor plate (7) and, on the other hand, slider lobes (80) which slide on the base plate (5) opposite the resistor plate (7). Hereby the central or potentiometer tapping is effected electrically at this base plate (5) and the soldering lug (51) connected to the same.
