Spring element

A springy contact element arrangement to be arranged between electrically conducting housing parts (10, 20), wherein a first housing part (20) comprises a sheet metal (1) which is configured to be shaped and has a sheet metal tab (2) located within a slot (11) of the sheet metal (1) and forming a unitary part of the sheet metal (1), wherein the sheet metal tab (2) is cold formed to form a springy contact element and wherein the sheet metal tab (2) has a thickness (d) reduced relative to a thickness of the sheet metal (1) by cold forming the springy contact element, wherein the springy contact element has an arc-shaped tab portion (4) projecting out of a plane (16) of the sheet metal (1), wherein the springy contact element has a base portion (3) and is connected with the base portion (3) to the sheet metal (1), wherein the springy contact element has a support area (21) located at a spacing relative to the base portion (3), wherein the support area (21) of the springy contact element is configured to be supported on at least one support surface (22) of the sheet metal (1), wherein the at least one support surface (22) of the sheet metal (1) extends transversely to a longitudinal tab axis (13) of the sheet metal tab (2) away from a first longitudinal slot edge (23) and engages underneath the support area (21).
