| 1. A multipurpose pseudospark switch comprising:
a hollow cathode comprising a base and an aperture opposite the base, wherein the base of the hollow cathode comprises a planar,
spiral electrode on a non-conducting support material;
an anode electrically insulated from the hollow cathode, located opposite the aperture of the hollow cathode and separated
a gap distance there from;
means for selectively applying a potential between the hollow cathode and the anode, and selectively applying a potential
to the planar spiral electrode; and
a sealed housing enclosing the hollow cathode, anode, and a gas.
