A backlit operating portion of a control device includes a veneer having indicia defining an open portion exposing a backlit component, a floating portion, and one or more ribs that suspend the floating portion. The rib defines an upper surface recessed relative to a front surface of the veneer, and opposed sides that extend from a base of the rib to the upper surface, such opposed sides tapered between the base and the upper surface, such that the upper surface is narrower than the base.

The present invention relates to a lighting device for a button, in which light incident into a light guide is prevented from leaking to a spacing clearance between a button unit and a light guide by a reflection layer, thereby enabling a lighting through the light guide to shine cleanly and uniformly to the outside.

A method for patterning an amorphous alloy is provided. The method includes forming a pattern for defining an amorphous alloy deposition region on a parent material, forming an amorphous alloy deposition layer on the parent material with the pattern formed thereon, and etching a region except for the amorphous alloy deposition region. A dome switch is provided. The dome switch includes a metal layer shaped like a dome, a central portion of which protrudes, and, in response to external force being received through the protruding central portion, the central portion contacting and electrically connected to a circuit board, and an amorphous alloy layer disposed on the metal layer. Accordingly, an amorphous alloy structure with enhanced durability and reliability is easily manufactured.

A control device includes one or more buttons having an illuminated indicia indicating a function. Each button has a translucent button body and an associated lighting element. A veneer covers a front surface of the button body, the veneer being opaque to block transmission of light through the veneer except for an area defining the indicia. The control device may further comprise a button lighting circuit, wherein the button lighting circuit and the associated lighting element are configured to operate at a first illumination intensity and a second illumination intensity. Selection of the button by a user, such as by pressing the button, results in the selected button displaying a greater illumination intensity.

A veneer may be configured to be secured to a backlit button of a control device. A plate portion of the veneer may have one or more indicia machined therethrough. The indicia may define an open portion, a floating portion, and one or more ribs that suspend the floating portion. The one or more ribs may be configured to create an optical illusion that conceals the ribs from view relative to a user of the control device. The rib may define an upper surface that is recessed relative to a front surface of the veneer, and may define opposed sides that extend from a base of the rib to the upper surface. The sides may be tapered between the base and the upper surface, such that the upper surface is narrower than the base. The sides and the upper surface of the rib may be unfinished.
