CA 2359364

A touch switch apparatus (20) for detecting the presence of an object such as a human appendage, the apparatus having a touch pad (22) and a local control circuit (26) connected to the touch pad and to a control device. The touch pad preferable includes a first electrode (E1) and a second electrode (E2) spaced from and surrounding the first electrode. The control circuit (26) is preferably in integrated circuit form. A signal is provided to the touch pad (22) to generate an electric field thereabout. Introduction of a stimulus near the touch pad (22) disturbs the electric field. The control circuit detects the electric field disturbance in and generates a control signal in response.

L'invention se rapporte à un appareil (22) doté d'un interrupteur à effleurement, qui est conçu pour détecter la présence d'un objet tel qu'un appendice humain et comporte un pavé tactile et un circuit de commande local (26) relié audit pavé tactile et à un dispositif de commande. Ledit pavé tactile comporte de préférence une première électrode (E1) et une seconde électrode (E2) entourant ladite première électrode et disposée à distance de celle-ci. Le circuit de commande (26) prend de préférence la forme d'un circuit intégré. Un signal qui est délivré au pavé tactile génère autour dudit pavé un champ électrique. L'apparition d'un stimulus à proximité du pavé tactile perturbe le champ électrique. Ledit circuit de commande détecte la perturbation du champ électrique et génère en conséquence un signal de commande.
