Abstract

L’invention concerne un dispositif de saisie capable de produire un clic adéquat en dépit de l’isolation optique d’une région d’éclairage visant à supprimer les effets indésirables de fuites de lumière réciproques. Une première région d’éclairage (7A) est isolée d’une seconde région d’éclairage (7B) au moyen d’une paroi pare-lumière (7c), de manière à supprimer les effets indésirables d’une fuite de lumière d’une des régions d’éclairage vers l’autre. Une protubérance (7d) est par ailleurs conçue pour comprimer le sommet d’un dôme (5A) situé au centre de la paroi pare-lumière (7c). Il est donc possible de produire un click adéquat en dépit de l’isolation optique de la première région d’éclairage (7A) vis-à-vis de la seconde région d’éclairage (7B) réalisée par la paroi pare-lumière (7c).
