| 摘要 |
The invention relates to a service switching device (1) having a housing (8). The housing comprises a face side (3), a fastening side and a narrow side (6) lying therebetween. A connection terminal (10) is held in a terminal accommodating area of the housing (8) which is located in the vicinity of the narrow side (6) . Said connection terminal comprises a clamping screw (24), which is accessible from the face side (3), having an actuating end (26) and a clamping end (30) opposite said actuating end. It further comprises a clamping body (12), in which a busbar and/or a connecting conductor can be pressed against a conductor bar (36) by means of the clamping screw (24), the clamping body (12) being accessible via a first housing opening (91) in the wall of the narrow side (6) . The clamping area can be covered by a terminal covering part (60) . Said terminal covering part is coupled to the clamping end (30) of the clamping screw (24) and can be carried along thereby in the movement direction (50) of the clamping screw (24) . It points in the direction of the face side (3) and is dimensioned such that it still completely covers the clamping area even when the clamping screw (24) has been screwed onto the conductor bar (36).
