Abstract

An operating element having an end piece, which is arranged for connecting to a printed circuit board and a front plate. An operating lever is rotatably mounted on the end piece. The operating lever has at least one grip section and one on and/or off lever piece, which are at least partly made from a wear-resistant material. Such a design has the particular advantage that part of the operating element which performs an on and/or off lever action, the on and/or off lever piece, opposite the section of the operating element to manipulate, the handle, is at least partly made from a wear-resistant material. The complete unit is thus rendered significantly more robust without sacrificing ergonomics of the grip piece.
