Abstract
A switch with an open state and a closed state suitably includes a cantilever having first and second state corresponding to the open and closed states of the switch, respectively. The switch may also include a magnet configured to provide an electromagnetic field that maintains said cantilever in one of the first and second states. Various embodiments may also include an electrode or electrical conductor configured to provide an electric potential or electromagnetic pulse, as appropriate, to switch the cantilever between the first and second states. Various embodiments may be formulated with micromachining technologies, and may be formed on a substrate.
