    Abstract: A microelectromechanical structure, usable in an optical switch for directing a light beam towards one of two light guide elements, including: a mirror element (53), rotatably movable; an actuator (65), which can translate; and a motion conversion assembly (77), arranged between the mirror element (53) and the actuator (65). The motion conversion assembly (77) includes a projection (54) integral with the mirror element (53) and elastic engagement elements (73) integral with the actuator (65) and elastically loaded towards the projection. The elastic engagement elements (73) are formed by metal plates fixed to the actuator (65) at one of their ends and engaging the projection (54) with an abutting edge (73b) countershaped with respect to the projection (54).

    Abstract: A micro-electro-mechanical device (20) formed by a body (4) of semiconductor material having a thickness and defining a mobile part (23, 24, 31) and a fixed part (3, 25, 30). The mobile part is formed by a mobile platform (23), supporting arms (31) extending from the mobile platform to the fixed part (3, 25, 30), and by mobile electrodes (24) fixed to the mobile platform. The fixed part has fixed electrodes (25) facing the mobile electrodes (24), a first biasing region (3) fixed to the fixed electrodes, a second biasing region (30) fixed to the supporting arms (31), and an insulation region (6) of insulating material extending through the entire thickness of the body (4). The insulation region (6) insulates electrically at least one between the first and the second biasing regions (3, 30) from the rest of the fixed part.
