CA 2410454

A keypad has a substrate carrying an array of sense elements arranged to change state in response to keypad operation, a flexible cover disposed above the substrate and having an exposed surface defining an array of independent key regions, with combination key regions defined in interstices between adjacent independent key regions, and an array of discrete snap elements extending between the cover and the substrate and spacing the cover from the substrate.

L'invention concerne un clavier équipé d'un substrat comportant une série d'éléments capteurs qui changent d'état en réponse à des opérations de clavier, un couvercle flexible par-dessus le substrat, et une surface exposée qui définit un alignement de zones de touches indépendantes. Des parties combinées de zones de touches sont définies dans les intervalles entre zones de touches indépendantes adjacentes. Enfin, il existe une série d'éléments d'assemblage à enclenchement qui s'étendent entre le couvercle et le substrat, assurant un espacement entre le couvercle et le substrat.
