COUPLING MEMBER FOR ELECTRICAL SWITCHING DEVICE HAVING INERTIAL MASS ELEMENT

The invention relates to a coupling member (2) for an electrical switching unit, wherein the coupling member (2) comprises a first switching contact (4) for opening and closing an electrical contact having a second switch contact (6), wherein the first switching contact (4) is connected to a drive rod (9) which is mounted such that the drive rod can be moved in translation and which is operativelyconnected to an actuator (15), which causes a translational movement of the drive rod (9). The invention is characterized in that an inertial mass element (3) is provided, which is coupled by a spring element (5) to the coupling member (2). 本发明涉及种用于电气开关设备的耦连件(2)，其中，耦连件(2)包括用于打开并且闭合与第二开关触点(6)的电气接触的第开关触点(4)，其中，第开关触点(4)与推杆(9)连接，推杆能平动运动地支承并且与促动器(15)作用连接，促动器致使推杆(9)平动运动。本发明特征在于，设有惯性质量元件(3)，惯性质量元件通过弹簧元件(5)与耦连件(2)耦连。
