Method of manufacturing a contact element for modelling electrical circuits

A method of manufacturing a contact element for modelling of electrical circuits comprising the following steps:

• providing a sheet metal blank;
• stamping said sheet metal blank to obtain a hollow formed workpiece (1), having an inner hollow body (2) with a bottom (3), a shoulder (4), a support platform (5) for connecting wire (6), said support platform having sides (7) and (8);
• providing electrical connection of the connecting wire (6) to the inner hollow body (2),
• wherein
• an electroplated metal coating is applied onto the said hollow formed workpiece (1);
• a hollow formed workpiece (1) is placed in an injection mold;
• an outer casing (9) is formed by filling the mold with a polymer material under pressure creating the outer casing (9) outside the hollow body (2) with a shoulder and a support platform (5) with connecting wire (6);
• a permanent magnet (10) is pressed into the hollow (11) of the body (2).
