Abstract: An electrical contact for a conductive shaft such as a shaft for a moving coil in an electrical meter, the contact comprising a housing containing a mobile conductive medium such as mercury, which connects the shaft to an input or output conductor. The mobile conductive medium is normally retained within the housing by virtue of a small running clearance for the shaft. The contact is vibration proof within a range of acceleration forces and vibration frequencies Damping of the shaft may be effected by a liquid mobile conductive medium.

Abstract translation: 用于导电轴的电接触件，例如电表中用于运动线圈的轴，所述接触件包括容纳诸如水银的移动导电介质的壳体，所述移动导电介质将轴连接到输入或输出导体。 移动导电介质通常由于轴的小的运行间隙而保持在壳体内。 触点在加速力和振动频率的范围内是防振的。轴的阻尼可以由液体移动导电介质来实现。
