Abstract

A device is provided which includes a substrate arranged in an interior thereof having a light emitting element positioned on an upper surface of the substrate; and a push button assembly disposed in an exterior structure of the device above the emitting element. The button assembly includes a cylindrical light guide for receiving/guiding light to an annular display part disposed on an upper portion of the light guide. The light guide is further defined by a lower end, and an inner and outer wall. A portion of the outer wall proximate to the lower end has a tapered surface portion. A push button part is movably disposed within the light guide. The emitting element is positioned coincident with a center axis of the light guide. Light emitted by the element is received by the light guide, reflected by the tapered portion, and guided towards the display part.
