Abstract:
A microrelay comprising:a micromachined deflectable actuator having first and second actuator surfaces and first and second conductive regions electrically isolated from each other; a first cap having a first cap surface adjacent the first actuator surface, the first cap having third, fourth and fifth conductive regions electrically isolated from each other, the third conductive region being adjacent the first conductive region, the fourth and fifth conductive regions being adjacent the second conductive region; a second cap having a second cap surface adjacent the second surface of the actuator, the second cap having a sixth conductive region adjacent the first conductive region; the actuator being deflectable in a first direction to allow the second conductive region to contact the fourth and fifth conductive region, and the first and third conductive regions to not electrically contact each other; the actuator being deflectable in a second direction opposite the first direction so that the first and sixth regions move closer without electrically contacting each other; the actuator being hermetically sealed within the microrelay, the first, third, fourth, fifth and sixth conductive regions being electrically accessible externally to the microrelay.
