Abstract
A MEMS device comprises first and second opposing electrodes (), wherein the second electrode () is electrically movable to vary the electrode spacing between facing first sides of the first and second electrodes. A first gas chamber () is provided between the electrodes, at a first pressure, and a second gas chamber () is provided on the second, opposite, side of the second electrode at a second pressure which is higher than the first pressure. This arrangement provides rapid switching and with damping of oscillations so that settling times are reduced.
