Abstract
Cross-field switch tube has three electrodes to define two concentric annular inter-electrode spaces. A magnet produces a field in both spaces, which field extends out of the switch tube through the electrodes. Circuit connects electrodes so that, with one circuit polarity, the electrode on the outside of one gap is a cathode while, with the other polarity, the electrode on the outside of the other gap is cathode for offswitching a load at any point of the AC cycle.
