An electrostatic relay comprises at least one fixed base having a fixed electrode and an actuator frame having a movable electrode. The fixed base carries a pair of fixed contacts insulated from the fixed electrode. The movable electrode carries a movable contact insulated from the movable electrode. The movable electrode extends along the fixed electrode and is pivotally supported at its one longitudinal end relative to the fixed base so as to pivot between two contacting positions of closing and opening the movable contact to and from the fixed contacts. The movable contact is formed at the other longitudinal end of the movable electrode. A control voltage source is connected across the fixed electrode and the movable electrode to generate a potential difference therebetweeen for developing an electrostatic force by which the movable electrode is attracted toward said fixed electrode to move into one of the two contacting positions. The electrostatic relay is characterized in that the movable electrode is cooperative with the fixed electrode to define therebetween an elongate gap which is narrower toward the one longitudinal end about which the movable electrode pivot than at the other longitudinal end of the movable electrode at which the movable contact is carried. |

A switch assembly includes first and second contact members which are operatively provided to take one of two positions, a break-position in which the first and second contact members are separated from each other, and a make-position in which the first and second contact members are electrically connected with each other. Magnetic members are provided operatively in association with the first and second contact members to define a closed magnetic loop with a current path extending through the loop, when the first and second contact members are turned to the make-position. The magnetic members attract each other by the magnetic flux through the closed loop to maintain the first and second contacts in the make-position when the current flowing through the current path is not zero. Thus, the first and second contact members are permitted to return to the break-position at a zero crossing point of a.c. current flowing through the contacts. |

| PROBLEM TO BE SOLVED: To provide an electret applied device having little nonuniformity in performance, and a manufacture thereof. SOLUTION: This device is prepared by joining a fixed piece 20 having a fixed electrode with a movable piece 10 having a movable part 10a' functioning also as a movable electrode.

| PURPOSE:To provide an electrostatic driving relay wherein applied voltage to an electrode is required low to obtain good contact reliability also high intercontact dielectric strength by sufficiently obtaining a contact pressure. CONSTITUTION:Fixed chips 1, 3 in upper/lower parts are formed of silicon wafers formed with fixed electrodes 10, 30. Also a movable chip 2, interposed between the fixed chips 1, 3, is formed of silicon monocrystal wafers formed with a movable electrode 21, and it is movably supported.

| PURPOSE:To accomplish an electrostatic relay of such a structure that its possibility of practical application is not, impaired even in the single mode and that it is easy to secure a requisite and sufficient electrostatic power when a driving voltage is impressed. CONSTITUTION:An electrostatic relay concerned is equipped with a stationary side base 2, which has a stationary contact 21 and a stationary side driving electrode 11, and a movable plate 13 having a movable contact 22 and a movable side driving electrode, wherein such an arrangement is introduced that see-saw motions are possible in the condition the movable plate 13 confronts the stationary side base 2. The movable contact 22 is positioned facing the stationary contact 21 at least on one side viewed from the fulcrum P of the see-saw motions, and the stationary side driving electrode 11 and movable side driving electrode confront on the two sides of the fulcrum P, and at either of these two electrodes, an electret 9 is installed for drawing one side of the movable plate 13 to the stationary side when the driving voltage is out of impression. Thus the see-saw motions are generated in the movable plate 13, wherein the other side of the movable plate 13 is drawn to the stationary side while the driving voltage is impressed on the driving electrodes. | ||||||
