  • Patent number: 11425835
    Abstract: A switching device includes a number of line sections corresponding to a number of phases, each including a first and a second connection part, for connection to a connection phase of an electrical consumer. At least one controllable semiconductor switching element is provided per phase, wired between the first and second connection part. A bypass unit includes one controllable electromechanical switching element with a low on-resistance per phase. The controllable electromechanical switching element is wired, in parallel with the controllable semiconductor switching element of this phase, between the first and second connection part. The first and second connection part of a respective phase are arranged adjacently on one side of the power module in spatial proximity in a direction of extent. A contact bridge, assigned to a respective phase, runs in the direction of extent in order to electrically connect the first and second connection part in the switched-on state.
