Abstract (en)

[origin: WO2022223803A1] The invention relates to a method for producing a contact carrier (32) of an electrical switching contact, wherein the contact carrier (32) is formed by a number of layers of a metallic flat material arranged one on top of the other, comprising the following method steps - providing a strip-shaped metallic flat material (2), extending in a first longitudinal direction (4), wherein the flat material (2) has a transverse extent in a transverse direction (6) transverse to the first longitudinal direction (4) and a thickness extent orthogonal to its plane of extent, - performing a contour cut or die cut on the flat material (2) in such a way as to form successively in the first longitudinal direction (4) at least two flat-material portions (14), which remain joined to one another in the first longitudinal direction (4) by means of a connecting web (16), - leporello-like folding of at least two flat-material portions (14) onto one another about a folding axis (28), extending orthogonally in relation to the first longitudinal direction (4) in the region of the connecting web (16), to form the contact carrier (32).
