ABSTRACT:
A switch for providing a control function is provided. The switch is comprised of an actuator. The actuator comprises a base portion, a cantilever beam connected to the base portion, and an actuator cell adjacent to the cantilever beam. The actuator cell comprises a first metal electrode positioned on the cantilevered beam, a second metal electrode positioned near the first metal electrode, and phase change material between the first and second metal electrodes, wherein the phase change material connects the first metal electrode to the second metal electrode, wherein applying a burst of energy to the phase change material causes the phase change material to change between an amorphous state and a crystalline state, causing the cantilevered beam to move between a first position and a target position and wherein the cantilevered beam remains at the target position upon removal of the energy thereby activating the control function.
