ABSTRACT:
A binary indicator including a pair of indicator discs mounted along a common axis has means for damping rotational movement of a resetting structure in one direction following movement imparted to the resetting structure in the other direction for purposes of resetting the relative positions of the indicator discs to their relative positions prior to their relative relocation occasioned by a fault or malfunction condition. One indicator disc undergoes movement, the movement in both directions being induced magnetically. And, movement of the resetting structure in the other rotational direction is against the forces of rotational elasticity of spring means. A force for damping rotational movement of the resetting structure in the one rotational direction is developed by viscous-shear frictional engagement between a pair of friction discs biased into juxtaposition with a viscous film therebetween by the spring means under compression.
