Abstract:
1. An electrostatically actuated micro-mechanical switching device, comprising: movable elements formed in a bulk of a substrate for closing and releasing at least one Ohmic contact by a horizontal movement of said movable elements in a plane of the substrate, including: a drive with comb-shaped electrodes, said electrodes including fixed driving electrodes and movable electrodes; a movable push rod mechanically connected with said movable electrodes and extending through said comb-shaped electrodes; at least one restoring spring mechanically connected with said push rod; a signal line having two parts interrupted by a gap; a contact element mechanically connected with one side of said push rod, said contact element including a movable contact beam extending at least partially opposite said signal line and being electrically and mechanically connected to each of said two parts of said signal line; a ground line having at least one contact bar extending through said gap in said signal line for forming the Ohmic contact between said contact beam and said ground line; and a contact metallization formed at least on top and on side walls of said contact beam, of said signal line, and of said ground line; and wherein the switching device is in shunt-configuration for closing and releasing the Ohmic contact between said ground line and said signal line.
