A DC matrix power switch structure electrically connects m DC power modules to n charge dispensers for charging electric vehicles. The matrix includes an input structure having m conducting input busbar pairs and an output structure having n conducting output busbar pairs. A first busbar of m input busbar pairs is connected to a positive voltage terminal and a second busbar of m input busbar pairs is connected to a negative voltage terminal of each of m DC power modules. A third busbar of n output busbar pairs is connected to a positive voltage terminal and a fourth busbar of n output busbar pairs is connected to a negative voltage terminal of each of n charge dispensers. The combination produces two times m×n busbar crossing points. A power switch, when activated, electrically connects to the associated busbar at the busbar crossing point.

A DC matrix power switch structure mechanically and electrically connects m DC power modules to n charge dispensers for charging electric vehicles. The matrix includes an input structure having m conducting input busbar pairs and an output structure having n conducting output busbar pairs. A first busbar of n output busbar pairs is connected to a positive voltage terminal and a second busbar of n output busbar pairs is connected to a negative voltage terminal of each of n charge dispensers, producing two times m×n busbar crossing points. A power switch is mechanically mounted to a cross point or is moved to a crossing point and, when activated, connects to the associated busbar at the busbar crossing point providing power to the appropriate charge dispenser. A power switch includes one or more actuators to connect an input busbar to an output busbar with a flexible conductor.

A switching and/or distributing device has at least one receiving housing and a housing cover. Arranged in at least one housing rail region are one or a plurality of power distribution rails which extend substantially in a main plane and arc connected to sub-distribution rails. In at least a first plane, said sub-distribution rails extend substantially in parallel to the main plane and arc electrically insulated from one another and extend in the direction of at least one housing component region, wherein in the housing component region, in particular modular components, which contain electrical/electronic operating means, arc in electrical contact with one sub-distribution rail each. As a result, a switching and/or distributing device is improved in such a way that the arrangement of corresponding components is possible easily without much additional effort even in potentially explosive atmospheres and a plurality of components of different ty pes and of different sizes can be arranged at the same time.
