Patent ID: 8592707

Claim:
An electrical switch for electrically coupling an electrical conductor to a busbar, the electrical switch comprising a contact element mounted on a shaft, with a drive for opening and closing the switch causing the shaft to rotate, wherein the contact element comprises two contact surfaces of which, in a closed switch position, a first one of the contact surfaces is in contact with the busbar and a second one of the contact surfaces is in contact with a conductor disposed on the housing, wherein the contact element is mounted on the shaft so that the entire contact element is radially displaceable with respect to a longitudinal axis of the shaft, wherein the contact element has a longitudinal axis about which the contact element is mounted tiltably and displaceably in a direction of said longitudinal axis of the contact element, in a bearing part or guiding part; an adjustment device configured to adjust the contact element when the switch is closed and opened, wherein the adjustment device is configured to rotate the contact element about an axis for opening and closing the switch; and a guiding part, wherein the guiding part comprises resting surfaces configured obliquely relative to a shaft axis of the shaft, wherein the contact element, because of the resting surfaces, is configured to first pivot about a longitudinal axis of the contact element defined by a connecting line of its contact surfaces when the switch is opened.
