Claim 12:
13. A power semiconductor module, comprising:
an arrangement, further comprising:
a housing and an electrically conductive contact spring;
the contact spring has a first orthogonal main plane and a second orthogonal main plane along its specified spring direction;
the contact spring is formed so as to be symmetric with respect to the first orthogonal main plane, an x-z plane, and to be asymmetric with respect to the second orthogonal main plane, an x-y plane, and also with respect to a rotation through 180° about a specified spring direction;
the housing has a spring shaft for receiving the contact spring, and wherein the spring shaft has a first main plane and a second main plane, which coincide with the respective first and second orthogonal main planes of the contact spring, and wherein the spring shaft is formed so as to be symmetric relative to both main planes; and,
the contact spring is arranged in a captive manner in the associated spring shaft by means of a first retaining means acting contrary to the specified spring direction;
wherein the contact spring, owing to the symmetry of the spring shaft with respect to its second orthogonal main plane, can be arranged in a non-twisted position in the spring shaft, and also twisted through 180° about its specified spring direction;
wherein the contact spring has a first and a second electrical contact portion and a spring portion arranged between them;
the first contact portion has a first contact surface arranged contrary to the specified spring direction, and
the second contact portion has a second contact surface arranged in the specified spring direction;
wherein the contact spring is arranged in a captive manner in the associated spring shaft by means of a second retaining means acting in the specified spring direction,
wherein the contact spring, which is preferably formed as a high-current contact element with a current carrying capacity of more than 10 A, is formed from a strip-like metal body with a rectangular cross section and deformations, in particular two S-shaped deformations, of this metal body for forming the spring portion;

a power electronic substrate, which has a trace; and
wherein the substrate is arranged in the housing.
