Abstract:
1. A microfabricated switch, comprising: a) a base layer; b) a moveable member layer substantially parallel to the base layer, having disposed therein a moveable member that is moveable between first and second positions, and where the moveable member is constrained to move substantially parallel to the base layer; c) first and second terminals, mounted relative to the moveable member such that when the moveable member is in the first position electrical current can flow between the first and second terminals; and d) an electromagnetic actuator comprising a coil, the electromagnetic actuator having north and south poles mounted such that the north and south poles are both disposed in the moveable member layer, and mounted relative to the moveable member such that the moveable member moves responsive to force applied from the electromagnetic actuator; wherein the electromagnetic actuator and moveable member collectively define a closed-loop path for magnetic flux.
