Abstract

A button assembly for displaying an illuminated symbol with a locking ring having an outer surface. A solid light guide is positioned within and spaced apart from the locking ring. The light guide has a top surface for displaying an illuminated symbol and a bottom surface with a light receiving member having a refracting surface with a first lens member for receiving and directing light to the top surface of the light guide. A resilient sealing member is mounted on the locking ring and interconnects the locking ring and the light guide. The sealing member has an unsupported portion that facilitates movement of the light guide relative to the locking ring.
