ABSTRACT:
A switch for coaxial circuits is shown, including a moveable contact, a controller which controls the position of the moveable contact, and a latch to hold the moveable contact in the latest position determined by the controller. The moveable contact has an end which is permanently connected to a first terminal of a coaxial switch and a free end which may be connected to either of two other terminals of a coaxial switch as determined by signals to the controller. The controller includes a coil responsive to electrical current to magnetize an armature which is mechanically linked to the moveable contact. The latch includes a permanent magnet which reacts with a magnetized portion of the armature to force the armature and therefore the free end of the moveable contact into the latest position as determined by the polarity of the magnetic field of the coil.
