Abstract
A MEMS based optical switch comprises a bottom electrode, a cantilever electrode, and a top electrode, all of which overlay a carrier board. An absence of a voltage differential between the top and bottom electrodes locates the cantilever electrode in a neutral position between the top and bottom electrodes. A presence of a voltage differential between the top and bottom electrodes locates the cantilever electrode in a position biased toward either the top electrode or the bottom electrode.
