Abstract:
A micromachined structure comprising:an outer frame; an inner frame pivotally coupled to the outer frame, wherein the inner frame is rotatable about an axis of rotation from a first position to a second position relative to the outer frame when an external force is applied, and wherein the inner frame is biased to return to the first position in the absence of the external force; and latching means for maintaining the inner frame in the second position in the absence of the external force, said latching means comprising: a permanent magnet on he outer frame; and a magnetic material on the inner frame; wherein the inner frame has first and second sides relative to the axis of rotation; and the outer frame has a stop against which the inner frame rests in the second position, and said magnetic material is positioned on the first side of the inner frame that is closer to the stop when the inner frame is biased to the second position.
