ABSTRACT:
This invention concerns a magnetic switch assembly used for switching input and output signals between coaxial transmission lines connected to a body having a closed cavity in which terminals of the lines are exposed. One or more conductive contact members, which are the only moving parts in the cavity, bridge one or more pairs of line terminals in closed circuit portion. The contact members are moved magnetically from open to closed position, and are latched or held failsafe by stationary permanent magnets or pulsed electromagnets. The contact members are moved to open position by pulsed electromagnets or rotatable permanent magnets. The contact members comprise magnetized strips, magnetic strips, or nonmagnetic strips carrying magnets or magnetic members. The assembly can be arranged for single or multiple pole, single or multiple throw switching.
