A heated hydrogen storage device for a plasma switch includes a ring-shaped holder element having an inwardly directed, ring-shaped shoulder that forms an opening. The device also includes a first and a second metal disk, with the first metal disk having a cut-out portion. A heating element is arranged between the first and second metal disks and is insulated therefrom. The heating element forms a turned heating track and has one end contacting the second metal disk and a second end extending outside through the cut-out portion of the first metal disk. The first metal disk and the heating element are stacked one above the another and rests on the ring-shaped shoulder of the ring-shaped holder element. The second metal disk is connected to the holder element and it covers the opening of the holder element. The second metal disk also fixes the first metal disk and the heating element in position.

Hydrogen storage device for a plasma switch

A contact configuration, whose axially opposed contacts have a current-supplying stud, a cup-shaped contact carrier and a contact plate set up on the rim of the contact carrier, a support consisting of material with poor electrical conductivity being provided to mechanically stabilize the contact plate. The support forms a tubular supporting region and is located on a graduated circle whose diameter is at most equal to the diameter of the current-supplying stud. The diameter of the current-supplying stud thereby equals at least 50% of the external diameter of the contact carrier. The length of the support has a considerably smaller cross section in its middle than in its base and top region so that the ohmic resistance of the support is at least approximately one magnitude greater than the ohmic resistance of the contact carrier and contact plate.
