Abstract
L'invention concerne les systèmes de commande de fonction par pression du doigt sur une touche accouplée à un ou plusieurs voyants. L'addition au brevet principal consiste en l'adjonction, sur le capuchon de la touche, d'une bague, emmanchée ou collée, comportant, sur sa périphérie, une saignée ou gorge destinée à recevoir un joint d'étanchéité. La touche selon le brevet principal modifié par la présente addition est utilisable, en particulier, pour la réalisation de claviers à plusieurs touches étanches, avec signalisation lumineuse, dans un espace restreint
