To provide an electromechanical signal selection device which can be miniaturized and highly integrated and which can selectively output only a signal of a predetermined frequency without providing any sensitive vibration sensing mechanism, and electric equipment using the electromechanical signal selection device.A micro-vibrator serving as a resonator is provided. The micro-vibrator can be excited by an external force to excite vibration of the micro-vibrator. A material whose physical property is changed in accordance with a structural change is used as the micro-vibrator. Thus, a sensitive electromechanical signal selection device is obtained.

An electromechanical filter capable of attaining a size reduction and a higher integration and executing a high-sensitivity signal sensing is provided. A quantum device is used as a sensing portion to implement a fine and highly sensitive sensing. A microvibrator 101 that is able to resonate with an input signal, and a sensing electrode 103 arranged at a predetermined interval to the microvibrator are provided. Since a change in an electrostatic capacity between the microvibrator and the sensing electrode can be sensed, a high-sensitivity sensing mechanism that is hard to realize in the prior art can be achieved.

Disclosed is a switch having a movable electrode to be separately driven downward and upward to secure signal transmission efficiency and insulation capability and operate for signal connection and disconnect at a high speed. The switch comprises a movable electrode, a fixed electrode positioned beneath the movable electrode, and a movable electrode driving fixed electrode positioned on both sides of the movable electrode with respect to a length wise direction thereof. Inside surfaces of the movable electrode, concave and convex parts are formed to arrange on both sides fixed electrodes having the corresponding concave and convex parts with a space.

A switch comprises voltage applying means for providing direct current potentials to first to third beams arranged with a spacing slightly distant one from another, and electrodes for inputting/outputting signals to/from the beams. By controlling the direct current potential provided to the beam, an electrostatic force is caused to thereby change the beam positions and change a capacitance between the beams. By causing an electrostatic force between the first and second beams and moving the both beams, the first and second beams can be electrically coupled together at high speed. Also, an electrostatic force is caused on the third beam arranged facing to the first and second beams, to previously place it close to the first and second beams. When the electrostatic force is released from between the first and second beams, the second beam moves toward the third beam thereby releasing the first and second beams of an electric coupling.
