A touch switch apparatus for detecting the presence of an object such as a human appendage, the apparatus having a touch pad, an electric field generated about the touch pad and also having a preferably integrated and local control circuit connected to the touch pad and to a controlled device. Practical applications for touch switch apparatus, including use of touch switch apparatus in connection with other structure, in particular multiposition contactless switches, to emulate mechanical switches.

L'invention concerne un appareil commutateur tactile permettant de détecter la présence d'un objet, tel qu'un appendice humain. Ledit appareil comprend un pavé tactile, un champ électrique généré autour dudit pavé tactile et, de préférence, un circuit de commande intégré et local connecté au pavé tactile et à un dispositif commandé. Les applications pratiques consistent à utiliser cet appareil commutateur tactile en connexion avec une autre structure, en particulier, des commutateurs multiposition sans contact afin d'émuler des commutateurs mécaniques.
