Abstract
The rotating coaxial switch first lifts the switching circuitry, including portions of the ground plane, rotates it to a new position, and then lowers the switching circuitry in the new position to make new connections. Rotation is by a stepper motor. Lifting is by any convenient solenoid. Both these functions (lift and rotate) can be combined in a single actuator module. Development and use of a combination actuator module reduces the size and weight of the switch.
