Title
(EN) INPUT DEVICE WITH MULTIPLEXED SWITCHES
(FR) DISPOSITIF D'ENTREE A COMMUTATEURS MULTIPLEXES
Abstract
(EN)
An input device for a computer system includes a detection circuit (152) with first and second inputs (208, 210) capable of carrying first and second input signals. A user depressible switch (300) adapted to allow a user to interact with the computer system is placed in series with a rectification device (310) between the two inputs. The rectification device (310) being adapted to limit electrical current in a first direction between the first input (208) and the second input (210).
(FR)
Un dispositif d'entrée pour un système informatique comprend un circuit de détection (152) présentant des première et seconde entrées (208, 210) capables de porter des premier et second signaux d'entrée. Un commutateur (300) sur lequel peut appuyer l'utilisateur, adapté pour permettre à un utilisateur d'interagir avec le système informatique, est placé en série avec un dispositif de redressement (310) entre les deux entrées. Le dispositif de redressement (310) est adapté pour limiter le courant électrique dans un premier sens entre la première entrée (208) et la seconde entrée (210).
