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.
