1. an electrical rotary switch (1), it comprises shell (6), described shell accommodate be arranged to for can be around at least the first running contact (7a) of a rotation (A) rotation with the second running contact (7b) and accommodate at least the first fixed contact (8a), the second fixed contact (8b), the 3rd fixed contact (8c) and the 4th fixed contact (8d)The first fixed contact comprises and is arranged to by the contact portion (17a) of the first running contact contact and comprises the coupling part (18a) for connecting wire,The second fixed contact comprises and is arranged to by the contact portion (17b) of the second running contact contact and comprises the coupling part (18b) for connecting wire,The 3rd fixed contact (8c) is arranged to substantially relative with the first fixed contact with respect to described rotation, and comprises the contact portion being arranged to by the first running contact (7a) contact;

  • The 4th fixed contact (8d) is arranged to substantially relative with the second fixed contact with respect to described rotation, and comprises the contact portion being arranged to by the second running contact (7b) contact;

    Wherein, the first fixed contact and the second fixed contact are arranged to be offset on axial direction and angle direction with respect to described rotation,It is characterized in that, the first running contact is arranged to for contact respectively the first and the 3rd fixed contact and the second and the 4th fixed contact on the first spin orientation around described common rotation axis simultaneously with the second running contact, and be arranged to for preventing above-mentioned contact on the second spin orientation around described common rotation axisWherein, the contact portion (17a, 17b) of at least the first and second fixed contacts (8a, 8b) and coupling part (18a, 18b) with respect to rotation (A), on radial direction (R) and axial direction (z), be oriented (α

    , P) at an angle to each other.
