Electromagnetic relay assembly having a flat coil and whose armature assembly is formed with a deformable stem

Claim 1

A RELAY ASSEMBLY COMPRISING A GENERALLY FLAT CORE OF MAGNETIC MATERIAL HAVING A PAIR OF CORE LEGS EXTENDING IN PARALLEL SPACED RELATION IN THE GENERAL PLANE OF THE CORE; ENERGIZABLE ELECTROMAGNETIC WINDINGS CARRIED BY SAID CORE LEGS; AN ARMATURE ASSEMBLY IN THE GENERAL FORM OF A DOUBLE T INCLUDING AN UPPER CROSS ARM, A STEP PROJECTING CENTRALLY FROM SAID UPPER CROSS ARM, A STEM PROJECTING TO AND A LOWER CROSS ARM AT THE FREE END OF SAID STEM; A MAGNETIC ARMATURE MEMBER SUBSTANTIALLY COEXTENSIVE AND RIGIDLY MOVABLE WITH SAID UPPER CROSS ARM; MEANS CONNECTING SAID LOWER CROSS ARM WITH SAID CORE SO AS TO MOUNT THE ARMATURE ASSEMBLY FOR LIMITED DISPLACEMENT BETWEEN A POSITION IN WHICH END PORTIONS OF A SIDE SURFACE OF SAID ARMATURE MEMBER LATERALLY ENGAGE WITH END PARTS OF THE RESPECTIVE CORE LEGS UNDER MAGNETIC ATTRACTION WHEN THE WINDINGS ARE ENERGIZED, AND A DISENGAGED POSITION IN WHICH SAID ARMATURE MEMBER IS SPACED FROM SAID CORE LEGS; RELAY CONTACTS SUPPORTED AT LATERAL SIDES OF SAID RELAY ASSEMBLY OUTWARD OF THE RESPECTIVE CORE LEGS; AND CONTACT ACTUATING MEANS SUPPORTED FROM SAID UPPER CROSS LEG OF THE ARMATURE ASSEMBLY NEAR RESPECTIVE ENDS THEREOF FOR ACTUATING SAID CONTACTS ON DISPLACEMENT OF THE ARMATURE ASSEMBLY BETWEEN ITS SAID POSITIONS, SAID STEM HAVING TORSIONAL DEFORMABILITY FOR EQUALIZING THE ACTIONS OF SAID CONTACT ACTUATING MEANS UPON THE RESPECTIVE CONTACTS.
