    摘要: A knob assembly is utilized for selecting a desired function of electronic appliances. The knob assembly includes a front panel having a circular mounting hole at front thereof, a knob freely moved to a voluntary direction, and a front circuit board having tact switches disposed to be pressed by an operation of the knob. The front panel has a tension holder backwardly projected around the mounting hole. The holder consists of a first group of tension ribs vertically and horizontally located and a second group of tension ribs located between the first group of tension ribs, the first group of tension ribs being provided with a groove, respectively. The knob has a knob handle disclosed from the front panel, a rotational sphere inserted into the tension holder, and a contacting member, the rotational sphere being provided with projections on a periphery surface which are coupled with each groove of the first group of tension ribs. The knob is restored by a restoring fot group of tension ribs. The knob is restored by a restoring force of the tension holder to a standard position which allows the projections of the rotational sphere to be always coupled with each groove of the first group of tension ribs.
