Patent number: 11177082Abstract: The electrical switch includes three fixed contacts and a rotatable knife contact being connected with a permanent electrical connection to a third one of the fixed contacts and including at least one pair of longitudinal blades. The rotatable knife contact connects in a first switching position only a first one and a third one of the fixed contacts electrically together, and in a second switching position only a second one and a third one of the fixed contacts. The rotatable knife contact connects further in a zero switching position the first, the second and the third fixed contact electrically together.Type: GrantFiled: June 22, 2020Date of Patent: November 16, 2021Assignee: ABB Schweiz AGInventors: Patrik Rabb, Rainer Kolmonen

Patent number: 11101083Abstract: 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.Type: GrantFiled: March 16, 2020Date of Patent: August 24, 2021Assignee: ABB Schweiz AGInventors: Patrik Rabb, Rainer Kolmonen

Patent number: 11043342Abstract: A change-over switch including a frame having a first side wall and a second side wall, a first supply terminal, a second supply terminal, a load terminal, and at least one gas flow opening for discharging gasses from the frame. The second side wall faces substantially opposite direction relative to the first side wall. The change-over switch is adapted to selectively provide a first connection between the first supply terminal and the load terminal, and a second connection between the second supply terminal and the load terminal. The first supply terminal and the second supply terminal project from the first side wall, and the load terminal projects from the second side wall. The at least one gas flow opening is formed in the second side wall.Type: GrantFiled: March 16, 2020Date of Patent: June 22, 2021Assignee: ABB Schweiz AGInventors: Patrik Rabb, Rainer Kolmonen, Mikko Välivainio

Patent number: 11037739Abstract: The electrical switch includes two fixed contacts and a rotatable knife contact having a rotational axis and including at least one longitudinal pair of blades 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 includes a first contact pin and outer ends in the blades in the rotatable knife contact includes a second contact pin. 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.Type: GrantFiled: March 10, 2020Date of Patent: June 15, 2021Assignee: ABB Schweiz AGInventors: Rainer Kolmonen, Patrik Rabb
