ABSTRACT:
A micro-electro-mechanical switch is described. The switch comprises a substrate, with a signal transmission portion and an activation portion attached with the substrate. The activation portion includes an armature activation electrode positioned above a substrate activation electrode. The signal transmission portion includes a metal contact extending from a conducting transmission line and through a bottom insulating layer of the signal transmission portion, thereby being exposed for electrical contact. A mechanical linkage connects the activation portion with the signal transmission portion so that the activation portion and the signal transmission portion move in concert. When an activation signal is applied along the activation portion, both the activation portion and the signal transmission portion are drawn toward the substrate to a substantially closed position, where the metal contact of the signal transmission portion electrically contacts a signal transmission electrode.
