Abstract
Rails (6) are mounted on the insides of the side walls of a cuboid housing parallel to the top side of the housing. After the cover (1) has been mounted on the case bottom (2) of the housing, the rail (6) embraces with its U-shaped profile a seating support (7) which is opposite it and is joined to the case bottom (2). A plurality of sheet-metal strip springs (3) are introduced captively between the rail (6) and seating support (7).
