ABSTRACT:
A variable resistor and switch assembly which in combination constitute an electronic tuning element assembly, comprises a variable resistor section having a slider movable along a resistance element by means of a rotatable screw, an indicator section having a flexible ribbon which moves past a window in accordance with the movement of the slider, and a rotary band selection switch section coaxially provided about the screw shaft and having a terminal supporting plate in which first and second fixed terminals are provided, a frame having openings and snap-engaged with the terminal supporting plate, and a movable contact rotatably held between the terminal supporting plate and frame to connect the first and second fixed terminals. The movable contact is actuatable by an operation portion via the openings provided in the frame. In this resistor and switch assembly, the terminals are integrally formed with the terminal supporting plate to allow a reduction in the number of parts and to improve the production efficiency.
