摘要： A method is described for designing a micro electromechanical device in which the risk of self-actuation of the device in use is reduced. The method includes locating a first conductor in a plane and locating a second conductor with its collapsible portion at a predetermined distance above the plane. The method also includes laterally offsetting the first conductor by a predetermined distance from a region of maximum actuation liability. The region of maximum actuation liability is where an attraction force to be applied to activate the device is at a minimum.
