Abstract

Dispositif de détection de vibrations utilisable sur un appareil ou un véhicule pour détecter sa mise en marche et/ou son arrêt ainsi que son temps de fonctionnement. Il comporte un élément 1 en élastomère conducteur placé dans un logement 2 entre deux électrodes 4 et 5. L'électrode 5 est mobile et coopère avec la masselotte 7, rappelée en pression par un ressort 8, prenant appui sur le couvercle 9, pour agir en compression sur l'élément 1. Les deux électrodes sont reliées à une alimentation électrique et à un moyen de mesurer et/ou d'exploiter les variations de la résistance de l'élément 1 en fonction de la force exercée sur lui.
