DC VOLTAGE SWITCH

A DC voltage switch includes a first switch arranged at a first potential between a first terminal of the first switch and a second terminal of the first switch, a first discharging device which is arranged between the first terminal at the first potential and a third terminal at a second potential and includes a first switching element designed as a thyristor, and a second discharging device which is arranged between the second terminal and a fourth terminal at the second potential and includes a second switching element designed as a semiconductor switch that can be switched off. The respective discharging devices connect the first terminal and the third terminal and/or the second terminal and the fourth terminal, at least temporarily, when the DC voltage switch is being or has been switched off.
