Abstract

An element (20) for making an electric contact to another contact member (19) for enabling an electric current to flow between said element (20) and said contact member comprises a body having at least a contact surface thereof coated with a contact layer (21) to be applied against said contact member. This contact layer comprises a continuous film comprising a laminated multielement material having strong bonds, such as covalent or metallic bonds, within each atomic layer and weaker bonds, through larger bonding distance or for example as van der Waals bonds or hydrogen bonds, between at least some adjacent atomic layers thereof.
