ABSTRACT:
A microwave switch that is an S-switch or a C-switch or the like has an electromagnetic actuator and a plurality of armatures. The armatures moves simultaneously in a linear path in response to the electromagnetic actuator. The actuator has one permanent magnet for each aperture and the switch has at least one coil winding. When an electric current is passed through the winding, the armatures move into a closed or open position, as desired. The only moving parts in the switch are the armatures themselves. The switch does not contain any complex mechanical arrangement or return springs that have been found in previous switches. The mass and volume of the switch as well as the number of moving parts is greatly reduced when compared to previous switches. This is very important when the switch is used in satellites.
