Abstract: The MEMS switch comprises a substrate with signal-lines having fixed-contacts, a movable-plate with a movable-contact, a flexible support-member supporting the movable-plate, a static-actuator and a piezoelectric-actuator configured to contact the movable-contact with the fixed-contact. The movable-contact is provided at its longitudinal center with the movable-contact, and its both the longitudinal ends with static-movable-electrode-plate. The support-member is four strips disposed on portions outside of the both width ends of the movable plate. The strip extends along the longitudinal direction of the movable plate, provided with a first end fixed to the movable plate, and provided with a second end fixed to the substrate. The piezoelectric-element is disposed on an upper surface of the strip to be located at a portion outside of the width ends of the movable-plate. The piezoelectric-actuator is configured to develop the stress applied to the coupling-portion which is created between each the strip and the movable-plate.
