Abstract

La présente invention est du domaine de l'électronique. Elle a pour objet un dispositif de connection ou contacteur dit matriciel caractérisé principalement en ce qu'il comporte disposés sur une plaque rigide 13 du type circuit imprime une première pluralité de conducteurs longilignes tels que 14 et une seconde pluralité de conducteurs longilignes tels que 15 isolés de la première pluralité, et disposé sur une face d'une feuille déformable 18 au moins un élément conducteur 19 pour mettre en contact électrique les contacteurs tels que 14 et 15 lorsqu'une pression 25 est appliquée sur la feuille 18, une couche 20 de liquidé à constante diélectrique élevée séparant normalement la plaque rigide 13 de la feuille souple 18. Applications à la visualisation sur écran vidéo de tracés en coordonnées X Y à des fins professionnelles, didactiques ou distractives (jeux utilisant un écran de téléviseur)
