Abstract
The electrical switch includes a first and a second fixed contact, and a rotatable knife contact including at least one pair of blades being flexibly connected to each other and rotating around a rotational axis. A third fixed contact is positioned on an opposite side of the rotational axis in relation to the adjacent first and second fixed contact and a middle portion of the rotatable knife contact is electrically connected to the third fixed contact. The rotatable knife contact connects in a first switching position the first fixed contact and in a second switching position the second fixed contact to the third fixed contact.
