Abstract
A filter contact comprising an electric contact in the form of a metal rod surrounded by a filter element of tubular shape. The external face of the filter element is fitted with a first electrode and the internal face of the filter element is fitted with a second electrode which is connected to the electric contact, the two electrodes being isolated from each other. The filter element of tubular shape is constituted by a tubular varistor in which the second electrode has an extension on at least one lateral electrode face having a zone of rounded shape such that coating in this zone with an electrode paste known per se produces a deposit of substantially constant thickness.
