Patent ID: 7109641

Claim:
A low voltage micro switch comprising: a substrate having an actuating space formed by etching at a certain area therein; an actuating unit having a piezoelectric material extended in a cantilever beam shape from a portion of the substrate to the actuating space of the substrate and a bias electrode; a conductive signal line extendedly formed at a certain interval from one side of the substrate and having a disconnected portion; a switching unit formed at a supporting unit and connecting or disconnecting the disconnected portion of the conductive signal line according to the movement of the actuating unit; said supporting unit connected to the actuating unit and the switching unit, positioned in the actuating space, including a plate portion forming the switching unit and the connection portions connecting the plate portion and a cantilever of the actuating unit, and moving according to the actuation of the actuating unit; and one or more ground units formed at the substrate.
