Abstract: A switch assembly has a back-lit key assembly including an opaque plug, a transparent body lightable from below at least partially to one side of the plug, and a transparent fusing member securing the transparent body and opaque plug together with the fusing member for movement as a unit. A flexible, transparent keypad is secured beneath the key assembly for movement therewith. An electrical contact is secured to the keypad for movement therewith. A board may be disposed at least partially beneath the keypad, the board including a light source disposed at least partially beneath the keypad to illuminate the transparent body and an open electrical circuit adapted to be closed by the electrical contact when the keypad is flexed downwardly.
