Abstract

Touche programmable destinée à présenter des messages à un opérateur afin d'attirer son attention activement sur la touche. La touche comprend un affichage à cristaux liquides 10 pour présenter au moins un message en fonction du programme choisi, des moyens de création de messages 15, 16, 19, 20 sur l'affichage à cristaux liquides et des moyens propres à permettre à l'affichage à cristaux liquides d'être déplacé par translation d'une position à une autre. Dans un mode de fonctionnement type, l'affichage à cristaux liquides est initialement activé pour présenter un message à la position neutre de la touche. Lorsqu'on enfonce la touche, l'affichage à cristaux liquides est automatiquement réactivé pour présenter un second message. Application notamment aux machines électriques à clavier.
