Radio frequency (RF) switch comprising an electromagnet formed on a magnet, a transmission line formed on the electromagnet and having a ground line and a signal line, and a movable contact connected to either the ground line or the signal line and capable of electrically coupling the ground line with the signal line. The transmission line is capable of propagating a RF signal if the ground line is electrically decoupled from the signal line. Conversely, the transmission line is incapable of propagating a RF signal if the ground line is electrically coupled with the signal line. The electromagnet can comprise an electromagnetic coil, formed in a layer of dielectric material, electrically coupled to a current source. Preferably, the movable contact is capable of being magnetically actuated, and is latchable. The magnet, the electromagnet, the transmission line, and the movable contact can have dimensions at a micron order of magnitude. The transmission line can be a coplanar waveguide. The coplanar waveguide can include a ground plane positioned between a layer of dielectric material and the electromagnet. The coplanar waveguide can also include means to electrically couple the ground plane to the ground line.
