Abstract:
1. A micro-switching device comprising: a base substrate; a fixing member bonded to the base substrate; a movable part including a stationary end fixed to the fixing member, the movable part extending along the base substrate; a movable contact electrode provided on the movable part at a surface facing away from the base substrate; a pair of stationary contact electrodes each including a region facing the movable contact electrode, the stationary contact electrodes bonded to the fixing member; a movable driver electrode provided between the movable contact electrode and the stationary end on the movable part at a surface facing away from the base substrate; and a stationary driver electrode bonded to the fixing member and including an elevated portion having a region facing the movable driver electrode; wherein the elevated portion has a step structure including at least three steps which are facing the movable driver electrode, said at least three steps being closer to the base substrate as the steps are farther from the movable contact electrode, and wherein in a non-operating state, the movable part and the movable driver electrode are warped in a manner such that a distance between the movable driver electrode and one of said at least three steps is substantially equal to a distance between the movable driver electrode and another of said at least three steps.
