A service switching device is disclosed which includes a housing. The housing includes a face side, a fastening side and a narrow side lying therebetween. A connection terminal is held in a terminal accommodating area of the housing which is located in the vicinity of the narrow side. The connection terminal includes a clamping screw, which is accessible from the face side, having an actuating end and a clamping end opposite the actuating end. A clamping body, in which a busbar and/or a connecting conductor can be pressed against a conductor bar by the clamping screw, is accessible via a first housing opening in the wall of the narrow side. The clamping area can be covered by a terminal covering part. The terminal covering part is coupled to the clamping end of the clamping screw and can be carried along thereby in the movement direction of the clamping screw. It can point in the direction of the face side and can be dimensioned such that it completely covers the clamping area even when the clamping screw has been screwed onto the conductor bar.
