Switch
First Claim
1. A switch for switching over a signal propagation path by contacting or non-contacting a movable member to or from an electrode, the switch comprising:
- an input port for inputting a signal;
a movable member connected to the input port;
a first electrode for propagating the signal;
a first control power supply connected to the first electrode and for generating a first control signal;
a second electrode for blocking off the signal; and
a second control power supply connected to the second electrode and for generating a second control signal;
the first control power supply provides said first control signal to the first electrode, the movable member being displaced by a driving force generated based on a potential difference between the movable member and first electrode and a potential difference between the movable member and the second electrode, thereby being contacted to the first or second electrode, the movable member is vibrated in a state contacted on the first electrode or the second electrode, the first or second control signal is controlled to apply to the movable member a force in one direction corresponding to a magnitude of an overshot that the movable member displaces beyond a predetermined position.

Abstract
A switch for switching over a propagation path of external signal by contacting or non-contacting a movable member to or from an electrode. The switch comprises an input port for inputting an external signal, a movable member connected to the input port, a first electrode for propagating the external signal, a first control power supply connected to the first electrode and for generating a control signal, a second electrode for blocking the external signal, and a second control power supply connected to the second electrode and for generating a control signal. The first control power supply provides a control signal to the first electrode. The movable member is displaced by a driving force generated based on a potential difference between the movable member and first electrode and a potential difference between the movable member and second electrode, thereby being contacted to the first or second electrode.
