Abstract

Fault detector 10 contains permanent magnet 11 to provide a constant magnetic field. A plurality of cores 12 having a magnetic storage capability is set and reset by switchable windings. When set, the resulting magnetic field is opposite to the field established by magnet 11. Indicator 13 is mounted near detector 10 and subject to the generated magnetic field. Indicator 13 contains an encapsulated medium sensitive to magnetic fields which can be viewed through window 14. When the field is one direction, the viewed medium is continuous. Setting a core 12 results in the viewed medium being oriented in an opposite direction and projecting a different appearance.
