A cold-cathode, crossed field switch has a magnet system which generates a magnetic field that is radially-oriented about a switch axis and a planar electrode system which generates an axially-oriented electric field. These structures facilitate a switch whose capacitance, inductance and fabrication costs are all reduced from that of conventional cold-cathode, crossed-field switches. Magnets of the magnet system are arranged in two concentric annular rings with their north and south poles aligned either axially or radially. The planar electrode system includes a cathode, a source grid, a control grid and an anode which are arranged in a substantially parallel relationship.
