    • A switching device comprises a swinging element (1) that is able to move between two end positions (A, B). Holding electrodes (4, 5) are placed in end positions (4, 5). A control circuit (8) controls the switching by generating signals of suitable voltage. Swinging element (1) is attached in an elastic manner (for example, by a flexible rod 2) in such a way that the elastic return force which tends toward a zero position (0) has, in an essential amplitude range, a higher value than the electrostatic force of attraction created by the control circuit and holding electrodes (4, 5) and acts in the opposite direction, in such a way that the switching time of the swinging element is determined primarily by its natural frequency and not by the magnitude of the electrostatic force of attraction.

    • A capacitive type semiconductor accelerometer has an intermediate silicon plate of n type conductivity including a movable electrode constituting a pendulum mass formed within the intermediate silicon plate and supported thereby via a beam so as to permit movement in a direction perpendicular to its plane. A first conductive island is formed within the intermediate plate and is immovably supported thereby via a first insulating leg so as to be isolated therefrom, and an upper glass plate is anodic bonded to the intermediate silicon plate. A first stationary electrode is formed on the upper glass plate at the position facing one face of the movable electrode with a predetermined gap. A lower glass plate is anodic bonded to the intermediate silicon plate and a second stationary electrode is formed on the lower glass plate at the position facing the other face of the movable electrode with a predetermined gap. First, second and third pads are disposed in common on the lower glass plate at the outside of the intermediate silicon plate, the first pad being electrically connected to the first stationary electrode via a first thin film lead formed on the lower glass plate and the first conductive island, the second pad being electrically connected to the movable electrode via a second thin film lead formed on the lower glass plate and the intermediate silicon plate and the third pad being electrically connected to the second stationary electrode via a third thin film lead formed on the lower glass plate.
