The invention relates to a controlling of micromechanical elements. Especially the invention relates to the controlling of the micromechanical switches. According to a method for controlling at least one micromechanical element a first control signal and a second control signal are fed to the micromechanical element. The second control signal is arranged to set the micromechanical element to an active state and the first control signal is arranged to hold the micromechanical element in the active state. An arrangement for controlling at least one micromechanical element (402) contains at least means for generating at least a first control signal and a second control signal, means for raising a voltage level of at least the second control signal and means for feeding the first control signal and the second control signal with raised voltage level to the micromechanical element. By means of the invention lower voltage levels can be used in micromechanical applications.
L'invention concerne un procédé et un dispositif de commande destines à des éléments micromécaniques. L'invention concerne plus particulièrement un procédé et un dispositif de commande destinés à des commutateurs micromécaniques. Un procédé de commande destiné à au moins un élément micromécanique consiste à envoyer un premier et un second signal de commande à l'élément micromécanique. Ce second signal est conçu pour garder l'élément micromécanique dans un état actif. Un dispositif de commande destiné à au moins un élément micromécanique (402) comprend au moins un dispositif destiné à générer au moins un premier et un second signal de commande, un dispositif destiné à augmenter le niveau de tension du second signal de commande au moins, ainsi qu'un dispositif destiné à envoyer le premier et le second signal de commande avec un niveau de tension supérieur à l'élément micromécanique. L'invention permet l'utilisation de niveaux de tension inférieurs dans des applications micromécaniques.
