Abstract

L'invention a trait à un capteur destiné à détecter un contact avec un objet, qui comprend un dispositif de commutation comprenant un ou plusieurs contacts ponctuels qui produisent une modification de résistance électrique lorsque le style du capteur s'écarte de sa position de repos au contact de l'objet. Les organes de contact sont revetus d'une matière conductrice, chimiquement inerte et homogène afin d'entretenir une répétabilité mécanique et des caractéristiques électriques constantes du capteur.The invention relates to a sensor for detecting contact with an object, which comprises a switching device comprising one or more point contacts which produce a change in electrical resistance when the style of the sensor deviates from its rest position at object contact. The contact members are coated with a conductive, chemically inert and homogeneous material in order to maintain mechanical repeatability and constant electrical characteristics of the sensor.
