DEFINITION

Classification: 313/260

(under subclass 257) Discharge devices having the electrodes mounted in side by side, concentric or co-axial relation, one

end of the electrodes being positioned in substantially co-planar relation, an electrode spacer having the form of a plate or bar mounted in contact with the electrodes or electrode supports to maintain the electrodes in spaced relation with each other, the plate or bar extending across the ends of the electrodes.

SEE OR SEARCH THIS CLASS, SUBCLASS:

241, where the discharge device is also provided with a shield member which extends across the ends of the electrodes.

255, where the electrode supports are supported by both of two opposed or spaced parts of the envelope (e.g., double ended discharge devices).
