    Abstract: A switching device which comprises: a body (2) which has a first side wall (21) and a first end wall (23), the first side wall (21) being perpendicular in relation to a longitudinal direction, and the first end wall (23) is substantially perpendicular to the first side wall (21); and a first fixed contact (41) comprising an inner section (412) and an outer section (414), the inner section (412) having a thickness dimension, the outer section (414) protrudes from the first side wall (21) in the longitudinal direction. The first fixed contact (41) comprises a test terminal (11) which is integral to the inner section (412) and protrudes from the inner section (412) in a lateral direction, which is perpendicular to the longitudinal direction and an end wall plane defined by the first end wall (23), the test terminal (11) having a substantially planar test terminal surface (115), and the test terminal (11) has a thickness dimension which is parallel to the thickness dimension of the inner section (412), the thickness dimension of the test terminal (11) is substantially smaller than the thickness dimension of the inner section (412), the test terminal (11) is accessible from outside the body (2) from the direction of the first end wall (23), and the test terminal (11) is adapted to be connected to a female connector.

    Abstract: The electrical switch comprises two fixed contacts and a rotatable knife contact having a rotational axis (Z1-Z1) and comprising at least one longitudinal pair of blades (410) flexibly connected to each other. The two fixed contacts as well as the blades in the rotatable knife contact are of a first electrically conductive material composition. The first and the second fixed contact comprises a first contact pin (240) and outer ends in the blades in the rotatable knife contact comprises a second contact pin (440). The first contact pin and the second contact pin are of a second electrically material composition, which is different from the first material composition. The first contact pin and the second contact pin pass over each other during a switching event.

    Abstract: The electrical switch (500) comprises a first and a second fixed contact (100, 200), and a rotatable knife contact (400) comprising at least one pair of blades (410, 420) being flexibly connected to each other and rotating around a rotational axis (Z1-Z1). A third fixed contact (300) is positioned on an opposite side of the rotational axis (Z1-Z1) in relation to the adjacent first and second fixed contact (100, 200) and a middle portion (450) of the rotatable knife contact (400) is electrically connected to the third fixed contact (300). The rotatable knife contact (400) connects in a first switching position the first fixed contact (100) and in a second switching position the second fixed contact (200) to the third fixed contact (300).
