Abstract

La présente invention concerne un générateur de signaux électriques. Il comprend un substrat en matière conductrice formant une première électrode, une couche de matière céramique appliquée sur un côté dudit substrat, une zone de matière conductrice sur la surface exposée de la matière céramique et formant une seconde électrode et un moyen conducteur électrique attaché à la première et à la seconde électrode. La présente invention est par exemple utile comme sélecteur d'étages d'un ascenseur.
