摘要： A MULTIPLE CONTACT ELECTROMAGNETICALLY OPERATED SWITCH HAVING A HOUSING THAT PROVIDES AN ENCLOSURE FOR THE ELECTROMAGNET OPERATOR OF THE SWITCH. THE HOUSING INCLUDES AT LEAST ONE METAL PART THAT HAS A HIGH COEFFICIENT OF THERMAL CONDUCTIVITY SO THE HOUSING ACTS AS A HEAT SINK AND A RADIATOR FOR HEAT GENERATED WITHIN THE ELECTROMAGNET WHEN A MAGNET COIL OF THE ELECTROMAGNET IS ENERGIZED. THE HEAT SINKING CAPABILITY IS ACCOMPLISHED BY RESILIENTLY SUPPORTING A PORTION OF A MAGNET CORE FOR THE ELECTRO-

MAGNET ON THE METAL HOUSING PART IN A MANNER WHICH WILL PERMIT THE MAGNET CORE TO MOVE TOWARD THE ARMATURE PORTION OF THE ELECTROMAGNET WHILE THE ARMATURE IS MOVING TOWARD THE MAGNET CORE TO REDUCE THE IMPACT SHOCK WHICH OCCURS WHEN THE ARMATURE ENGAGE THE MAGNET CORE.

摘要： A MULTIPLE CONTACT ELECTROMAGNETICALLY OPERATED SWITCH HAVING A HOUSING THAT PROVIDES AN ENCLOSURE FOR THE ELECTROMAGNET OPERATOR OF THE SWITCH. THE HOUSING INCLUDES AT LEAST ONE METAL PART THAT HAS A HIGH COEFFICIENT OF THERMAL CONDUCTIVITY SO THE HOUSING ACTS AS A HEAT SINK AND A RADIATOR FOR HEAT GENERATED WITHIN THE ELECTROMAGNET WHEN A MAGNET COIL OF THE ELECTROMAGNET IS ENERGIZED. THE HEAT SINKING CAPABILITY IS ACCOMPLISHED BY SUPPORTING A PORTION OF A MAGNET CORE FOR THE ELECTROMAGNET OF THE METAL HOUSING BY A PAIR OF EARS THAT ARE LOCATED ADJACENT THE POLE FACES OF THE MAGNET CORE TO MIXIMIZE THE TRANSFER OF HEAT BETWEEN THE MAGNET CORE AND THE HOUSING. THE EARS EXTEND FROM A MEMBER THAT IS CENTRALLY LOCATED IN THE STACK OF LAMINATED PIECES OF MAGNETIC IRON FORMING THE MAGNET CORE. A MEMBER PROVIDING THE CONNECTION BETWEEN THE ARMATURE AND A BELL CRACK LEVER EXTENDS CENTRALLY IN THE STACK OF LAMINATED PIECES OF MAGNETIC IRON FORMING THE ARMATURE SO THE SUPPORT FOR THE MAGNET CORE AND THE OUTPUT OF THE ARMATURE ARE COPLANAR WITH RESILIENT MEMBERS CARRIED BY THE MEMBER PROVIDING THE CONNECTION BETWEEN THE ARMATURE AND BELL CRACK ABSORBING THE SHOCK WHEN THE ELECTROMAGNET IS DE-ENERGIZED.

摘要： A MULTIPLE CONTACT ELETROMAGNETICALLY ACTUATED CONTACTOR HAVING A BELL CRANK CONNECTION BETWEEN A MAGNET ARMATURE AND A MOVABLE CONTACT CARRIER. THE CONTACTOR INCLUDES AN ARRANGEMENT WHEREBY THE ELECTROMAGNET AND THE CONTACTS ARE ENCLOSED IN SEPARATE HOUSING. THE HOUSING FOR THE CONTACTS INCLUDES AN INSULATING BASE AND A BARRIER WHICH ACTS AS A COVER FOR THE BASE AND COOPERATES WITH THE BASE TO PROVIDE A ROW OF COMPARTMENTS. EACH OF THE COMPARTMENTS HAS A PAIR OF STATIONARY CONTACTS AND A MOVABLE CONTACT THEREIN AND THE WALLS OF THE COMPARTMENTS PROVIDE A HIGH DEGREE OF INTERPHASE ISOLATION BETWEEN THE CONTACTS IN ADJACENT COMPARTMENTS. THE MOVABLE CONTACTS ARE OPERATED BY A U-SHAPED CONTACT CARRIER THAT IS MOVABLE IN A SLOT IN A REAR WALL OF THE BASE AND HAS PORTIONS EXTENDING THROUGH OPENINGS IN THE REAR WALL INTO THE COMPARTMENTS. THE CONNECTION BETWEEN THE BELL CRANK AND CONTACT CARRIER IS ARRANGED SO THAT THE BARRIER CAN BE REMOVED WHEN THE CONTACTS ARE SECURELY WELDED TOGETHER AND WILL CAUSE THE MOVABLE CONTACTS TO SEPARATE FROM THE STATIONARY CONTACTS DURING LIGHT WELDS BETWEEN THE CONTACTS.
