ABSTRACT:
An apparatus for simultaneously wetting a plurality of electrical contact areas with a liquid includes a punch with nubs or studs made of an elastomer. The number, configuration and dimensions of the nubs are adapted to the contact areas to be wetted. A process for simultaneously wetting a plurality of electrical contact areas with a liquid includes wetting the nubs with the liquid, leading the punch over the contact areas in such a way that the nubs are each disposed over one of the contact areas, and subsequently transferring the liquid from the nubs onto the contact areas.
