Abstract

L'invention a pour objet un circuit pour module de commande (100), en particulier pour habitacle de véhicule automobile, comportant : • un support (1) diélectrique, • au moins deux électrodes (E1, E2) capacitives de détection planes, associées à des touches capacitives (103), et disposées sur le support (1), • des pistes (5) électriques, disposées sur le support (1) diélectrique, destinées à relier séparément chacune des électrodes (E1, E2) capacitives à une unité de contrôle configurée pour modifier des paramètres et fonctions du véhicule lors de la détection d'un appui sur les touches capacitives (103), chaque piste (5) électrique présentant une longueur (ln) déterminée, caractérisé en ce que plus une électrode (E1, E2) capacitive est reliée à l'unité de contrôle par une piste (5) électrique de longueur importante, et plus sa superficie (Sn) est importante.The subject of the invention is a circuit for a control module (100), in particular for a motor vehicle interior, comprising: • a dielectric support (1), • at least two flat capacitive detection electrodes (E1, E2), associated to capacitive keys (103), and arranged on the support (1), • electrical tracks (5), arranged on the dielectric support (1), intended to separately connect each of the capacitive electrodes (E1, E2) to a unit control configured to modify parameters and functions of the vehicle upon detection of a press on the capacitive keys (103), each electrical track (5) having a determined length (ln), characterized in that plus one electrode (E1 , E2) capacitive is connected to the control unit by an electrical track (5) of considerable length, and the greater its surface area (Sn).
