    摘要: The first movable electrode is flat, but the second movable electrode is deformed into a convex shape. A dielectric layer is placed on the facing surface of the second movable electrode. By adjusting a voltage to be applied between the first movable electrode and the second movable electrode, an arbitrary distance is secured between the two electrodes by the electrostatic attractive force generated between the two electrodes, and a desired electrostatic capacitance is obtained. When the distance between the two electrodes is shortened, first, at the center, a part of the first movable electrode and a part of the second movable electrode come into contact with each other with the dielectric layer between them. Then, the first movable electrode and the dielectric layer (second movable electrode) come into contact with each other successively from the contact part towards the periphery side, and the contact area gradually increases.

    摘要: A micro-switching device includes a base substrate and a cantilever fixed to the base substrate via a spacer or anchor portion. The cantilever has an inner surface facing the substrate and an outer surface opposite to the inner surface. A conductive strip is formed on the outer surface of the cantilever. The switching device also includes a pair of stationary electrodes fixed to the base substrate. Each of the electrodes includes a downward contacting part spaced from the conductive strip on the cantilever. As the cantilever bends upward, the conductive strip is brought into contact with the contacting parts of the respective stationary electrodes.
