Title
(EN) INTEGRATED SWITCH AND BACKLIGHT ASSEMBLY
(FR) ENSEMBLE INTEGRE D'INTERRUPTEURS ET D'ECLAIRAGE D'ARRIERE PLAN
Abstract
(EN)
Integrated switch and backlight assembly includes a flexible light panel disposed between a circuit board and a keypad for backlighting the keypad. On the back side of the light panel is a back reflector having a plurality of contacts for selectively establishing electrical contact with the circuit board upon actuating selective portions of the keypad to cause corresponding portions of the light panel and back reflector to flex toward the circuit board.
(FR)
L'invention porte sur un ensemble intégré d'interrupteurs et d'éclairage d'arrière plan comprenant un panneau lumineux souple placé entre un circuit imprimé et un clavier pour éclairer le clavier par l'arrière. Le côté arrière du panneau lumineux comporte un rétroréflecteur présentant plusieurs contacts établissant sélectivement des connexions avec le circuit imprimé lors qu'on actionne des parties sélectionnées du clavier, ce qui entraîne une flexion des parties correspondantes du panneau lumineux et du rétroréflecteur vers le circuit imprimé.
