ABSTRACT:
A binary indicator for providing an indication of a normal or malfunction condition of equipment being monitored, the indicator having a magnetic latching and damping arrangement which ensures that the indicator functions properly under typical random high vibrational operating conditions. The latching and damping arrangement includes three auxiliary magnets which are located in close proximity to a rotating bar magnet to which a rotatable disc shaped indicator member is attached. The auxiliary magnets are positioned so that they prevent the rotating bar magnet from slipping out of the normal or "set" position into the malfunction or "fault" position or from slipping out of the "fault" position into the "set" position. Additionally, the auxiliary magnets dampen the movement of the rotating bar magnet when the bar magnet is reset to the "set" position from the "fault" position. The first auxiliary magnet is positioned in close proximity to a first end of the bar magnet when it is in the "set" position. The second auxiliary magnet is positioned in close proximity to the same first end of the bar magnet when the bar magnet is in the "fault" position. The third auxiliary magnet is positioned in close proximity to the second end of the bar magnet when it is between the "set" and the "fault" position but not exactly centered between these two positions.
