Abstract
Micro magnetic switching apparatus includes a permanent magnet supported on a base and a coil supported by the base so as to define a plurality of sides. A plurality of latching micro magnetic relays each includes a magnetic cantilever positioned to open a first electric circuit in a first orientation and to close the first electric circuit in a second orientation. One each of the relays is mounted adjacent each of the plurality of sides of the coil and adjacent the permanent magnet so as to be latched in one of the first and second orientations when the coil is not activated and to switch to the other of the first and second orientations when the coil is activated and to be latched in the other of the first and second orientations by the permanent magnet.
