A DC voltage switching device for coupling a DC voltage load via a positive and a negative conductor to a DC voltage source, wherein the positive and negative conductors are routed through the DC voltage switching device. The DC voltage switching device comprises



a first switching element for coupling and decoupling the DC voltage load, which is a semiconductor-based, electronically controllable switching element integrated in the positive or negative conductor;
a fuse integrated in the respective other conductor;
a sensor, at least for detecting the current flow of the conductor in which the first switching element is integrated: and
an evaluation device connected to the sensor and the first switching element, which is set up to compare the detected current flow with respect to a threshold value and to trigger the first switching element in order to disconnect the DC voltage load when the threshold value is passed.
