1. An electrical device, comprising:
a first printed circuit board including at least three protruding tab regions extending from an edge of the first printed circuit board and arranged in a circuit board plane of the first printed circuit board; and
a second printed circuit board including recesses; wherein each of the tab regions protrudes into a respective one of the recesses of the second printed circuit board;
wherein contact pins of the first printed circuit board are arranged parallel to the circuit board plane of the first printed circuit board, extend beyond the edge of the first printed circuit board, and protrude into holes in the second printed circuit board;
wherein a cross section of each of the recesses arranged in a circuit board plane of the second printed circuit board has four straight edge sections connected via semicircular edge sections;
wherein the tab regions are arranged along a first straight line and are spaced irregularly from each other; and
wherein the tab regions protrude further from the edge of the first printed circuit board in a direction parallel to the circuit board plane of the first printed circuit board than the contact pins of the first printed circuit board.
