Electromagnetic relays

Claim 1

IN A COMPACT MINIATURE ELECTROMAGNETIC RELAY, THE COMBINATION OF A HEADER COMPRISING A FLAT RECTANGULAR SUPPORT MEMBER AND A PLURALITY OF CONDUCTIVE PINS EXTENDING THERETHROUGH; A MOTOR STRUCTURE; MEANS MOUNTING SAID MOTOR STRUCTURE ON SAID SUPPORT MEMBER IN SPACED RELATION THERETO; AND A CONTACT ASSEMBLY INCLUDING FIXED AND MOVABLE CONTACTS CARRIED BY SAID PINS AND DISPOSED BETWEEN SAID MOTOR STRUCTURE AND SAID SUPPORT MEMBER, SAID MOTOR STRUCTURE COMPRISING AN ELECTROMAGNET HAVING AN ELONGATED MAGNETIC MATERIAL CORE EXTENDING PARALLEL TO SAID SUPPORT MEMBER AND A COIL SURROUNDING SAID CORE, SAID CORE BEING PARALLEL TO TWO OF THE SIDES OF SAID SUPPORT MEMBER AND OFFSET FROM THE CENTER OF SAID SUPPORT MEMBER TOWARD ONE OF SAID SIDES, A PAIR OF STRAIGHT FLAT MAGNETIC END MEMBERS COUPLED TO THE ENDS OF SAID CORE AND PROJECTING LATERALLY THEREFROM IN ALIGNED RELATION RELATIVE TO SAID CORE, A SUBSTANTIALLY STRAIGHT CONTINUOUS ELONGATED MAGNETIC STRUCTURE EXTENDING BETWEEN SAID END MEMBERS IN SPACED RELATION TO SAID ELECTROMAGNET, SAID CORE, SAID END MEMBERS AND SAID MAGNETIC STRUCTURE COOPERATING TO DEFINE A GENERALLY RECTANGULAR FLUX PATH PARALLEL TO SAID SUPPORT MEMBER, AND AN ELONGATED MAGNETIC MATERIAL ARMATURE DISPOSED FOR PIVOTAL MOVEMENT ABOUT AN AXIS PERPENDICULAR TO SAID SUPPORT MEMBER, SAID ARMATURE BEING DISPOSED BETWEEN SAID MAGNETIC STRUCTURE AND SAID ELECTROMAGNET WITHIN THE BOUNDS OF SAID RECTANGULAR FLUX PATH, AND MAGNETIC MATERIAL POLE PIECES BETWEEN SAID ARMATURE AND SAID COIL, SAID POLE PIECES BEING MAGNETICALLY COUPLED TO SAID END MEMBERS AND EACH PROVIDING A POLE FACE DIRECTED AWAY FROM THE AXIS OF SAID CORE; SAID SUBSTANTIALLY STRAIGHT ELONGATED MAGNETIC STRUCTURE COMPRISING A FIRST STRAIGHT PERMANENT MAGNET HAVING AN END SECURED TO ONE OF SAID END MEMBERS, A SECOND STRAIGHT PERMANENT MAGNET HAVING AN END SECURED TO THE OTHER OF SAID END MEMBERS, SAID PERMANENT MAGNETS EXTENDING TOWARD EACH OTHER AND TERMINATING AT FACING ENDS SPACED FROM EACH OTHER, AND MAGNETIC MATERIAL MEANS CONNECTING THE FACING ENDS OF SAID PERMANENT MAGNETS; ONE OF SAID PERMANENT MAGNETS BEING EFFECTIVE TO MAGNETICALLY LATCH SAID ARMATURE TO ONE OF SAID POLE FACES WHEN SAID ARMATURE IS IN A FIRST POSITION ENGAGING SAID ONE OF SAID POLE FACES AND THE OTHER OF SAID MAGNETS BEING EFFECTIVE TO LATCH SAID ARMATURE TO THE OTHER OF SAID POLE FACES WHEN SAID ARMATURE IS IN A SECOND POSITION ENGAGING THE SAID OTHER OF SAID POLE FACES.
