  • Electrostatically actuated micro-mechanical switching device
    Patent number: 8610520
    Abstract: An electrostatically actuated micro-mechanical switching device with movable elements formed in the bulk of a substrate for closing and releasing at least one Ohmic contact by a horizontal movement of the movable elements in a plane of the substrate. The switching device has a drive with comb-shaped electrodes including fixed driving electrodes and movable electrodes. A movable push rod is mechanically connected with the movable electrodes, extends through the electrodes, has a movable contact element at one side, and at least one restoring spring. A signal line has two parts interrupted by a gap. The micro-mechanical switching device is in shunt-configuration with low loss, high isolation in a wide frequency range, low switching time at low actuation voltage and sufficient reliability. The line impedance of the signal line and its variation is as small as possible. The switching device is in shunt-configuration for closing and releasing the Ohmic contact between a ground line and the signal line.
