scope:

This specification relates to design requirements for miniature tractive armature D.C. relays of the plug-in type for use in railway signaling circuits. The design is such that once the armature is attracted it is held in the full operate position by magnetic means after the operate coil is de-energised until released by energisation of a second independent winding.
