Abstract

Un commutateur de données (1) comprend un dispositif de commutation (2) et au moins deux ports aptes à se connecter respectivement à une source de données telle que l'Internet ou autre réseau, facultativement par l'intermédiaire d'un câble téléphonique, et à un dispositif électronique tel qu'un ordinateur. Le dispositif de commutation a au moins deux positions de commutation. Lorsque le dispositif de commutation est dans une première position de commutation, le premier port (3) est connecté électriquement au second port (4). Lorsque le dispositif de commutation est dans une seconde position de commutation, il y a un circuit ouvert entre les premier et second ports. Dans une application privilégiée, le commutateur de données permet à l'ordinateur d'être facilement connecté à, ou déconnecté de, l'Internet.
