ABSTRACT:
An electrical beam switch for interconnection between a plurality of inputs and outputs and includes a two-dimensional array of electrically charged particle emitters and an array of detectors facing the emitter array for receiving charged particles from various of the emitters. X and y electrical deflectors are positioned adjacent each of the emitters for directing the charged particles from each of the emitters to a selected one or more of the detectors. A screen lens may be positioned adjacent the array of detectors for focusing the directed beams on to the selected detector.
