Document Type and Number:

WIPO Patent Application WO/2007/125969

Kind Code:

A1

Abstract:

A micro machine switch is provided to switch electric connection between signal electrodes in response to a control signal from an outside. The control signal is comprised of a first control signal for connecting the signal electrodes for a signal to pass and a second control signal for cutting off the electric connection between the signal electrodes. The micro machine switch is provided with a substrate; a rotating member rotatably provided on the substrate; a movable electrode provided on the rotating member; a first signal electrode, wherein one end of the first signal electrode is connected with one end of the movable electrode while the other end is connected with the substrate; a second signal electrode provided around the rotating member at a position where the other end of the movable electrode is connected with the second signal electrode by rotation of the rotating member; and a driving unit for rotating the rotating member until a position where the other end of the movable electrode electrically is connected with the second signal electrode in accordance with the first control signal and for rotating the rotating member until a position where the other end of the movable electrode is electrically disconnected from the second signal electrode in accordance with the second control signal.
