Abstract

Un dispositif de télécommunication portable (10) comprend une carte à circuit imprimé electronique (20) agencé dans un boîtier (12), ainsi qu'un bloc (32) de touches, dont les touches individuelles (32) sont agencées, lorsqu'elles sont pressées, afin d'infléchir un dôme tactile respectif (52) sur une feuille (50) à dômes interposée entre le bloc de touche et la carte à circuit, de manière à établir un contact électrique avec un point de contact respectif (22) sur la carte à circuit. Le dispositif de télécommunication comprend des moyens de protection de la carte à circuit contre les décharges électrostatiques (DES). La feuille (50) à dômes se compose d'une plaque non conductrice formant un joint étanche à l'air et/ou électrostatique entre le bloc (32) de touches et la carte à circuit (20) de manière que la feuille à dômes fasse office de moyen protecteur contre les décharges électrostatiques.
