The disclosure relates to a service switching device having a housing, having a front face side, a rear face side, having front and rear narrow sides connecting the front and rear face sides, having lateral broad sides, a fastening side, having at least one screwless terminal connection, which is fixed in position in a terminal connection area in the interior of the housing, for connecting connecting conductors by fixedly clamping them with a clamping spring, which acts as a compression spring on the connecting conductor ends, fixedly clamps them in a window-like cutout of a busbar and has a number of spring elements which corresponds to the number of connecting conductors to be connected. The housing wall has, in the region of the terminal connection, a number of connection openings for in each case one connecting conductor which corresponds to the number of connecting conductors to be connected, and each connection opening is associated with a spring element in such a way that each connecting conductor can be clamped with the other connecting conductors against a common clamping edge of only one window-like cutout.
