Abstract
Spring-clips are pressed into push buttons to provide a stabilized and yieldable fit on the ends of cassette player control levers. This allows freedom of button movement, if needed, to enhance the assembly of the escutcheon-lens assembly to the cassette player-chassis assembly. Because of the great accumulation of tolerances between the escutcheon-lens assembly and the cassette player-chassis, the spring clips provide sufficient freedom of movement of the buttons relative to the levers, as needed, to improve the alignment of the buttons with corresponding openings in the escutcheon-lens assembly. Once the escutcheon-lens assembly is secured to the player-chassis assembly. This invention eliminates or reduces button rattle while imparting a firm feeling to the activation action of the button.
