Abstract
A micro-switching device includes a base substrate, a fixing member on the substrate, a movable part having an end fixed to the fixing member and extending along the substrate, a movable contact electrode provided on the movable part and facing away from the substrate, a pair of stationary contact electrodes bonded to the fixing member and including a region facing the movable contact electrode, a movable driver electrode between the movable contact electrode and the stationary end on the movable part at a surface facing away from the substrate, and a stationary driver electrode bonded to the fixing member and including an elevated portion having a region facing the movable driver electrode. The elevated portion is provided with steps facing the movable driver electrode, where the steps are closer to the substrate as they are farther from the movable contact electrode.
