Abstract
Because of their high MeO component, such small contact plates cannot be directly soldered or welded onto contact carriers. For this purpose, such a small contact plate must be provided with a layer which can be soldered or welded. According to the invention, it is proposed that such a layer be applied in the course of hot-press plating (hot-press welding), in an inert gas or reducing atmosphere. <IMAGE>
