Abstract
A latching electromagnetic RF switch is provided with an armature having a permanent magnet mounted thereon. An electromagnetic coil surrounding the armature has a ferromagnetic member mounted opposite the armature. A spring holds the permanent magnet away from the ferromagnetic member, latching the switch in a first position. In a second position, the permanent magnet attracts the ferromagnetic member and holds the armature against the force of the spring latching the switch.
