Abstract: A clutch knob that comprises a body portion and a cover portion. The clutch mechanism includes two integrally formed flexible and resilient sweeper arms attached to the base of the body portion; serrations with alternating smooth troughs and crests which are integrally formed on the inner circumference of the cover portion and the cover portion is fitted onto the body portion and so that the cover portion and the body portion are secured loosely with respect to one another. In addition, the body portion has two integrally formed flexible and resilient sweeper arms that are configured in the shape of pointed arches. The sweeper arms are integrally attached to the base and the circular platform. Further, the apex points of the arches are made smooth and made to point diametrically opposite one another. Moreover, the inner circumference of the serrations of cover portion are configured in the form of the alternating smoothened troughs and crest.

Abstract: An improved actuator button having components integrated therein which permit the single button to be operated in two distinct and mutually exclusive modes with each of the modes achieving respective separate functions. The improved actuator button advantageously incorporates a `press down` mode and a `slide` mode, which achieve separate functions with each operation of the modes. The features of the improved actuator button have general application in the manufacturing of electrical and electronic products. In particular, the improved actuator button has useful application in portable compact disk players (CD players) wherein the exclusively press mode operation of the actuator achieves the `open` function by opening the protective cover of the CD player, while the exclusively `slide` mode operation of the actuator achieves the `hold` function by preventing interruption of the currently played CD program.
