Abstract
Abstract A latching relay employing an electro-magnetic relay coil having associated therewith opposite end armatures. This relay coil receives operating power by way of an input contact member. One of the armatures carries a manually operated switch which also includes an end for actuating the closure contact. The opposite armature functions to assist in the manual switching and in its inactive state blocks operation of the primary armature. Another contact is associated with one of the armatures for providing high power transfer.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
118 words
A relay construction comprising; electro-magnetic means having opposite end poles, means coupling to said electro-magnetic means for receiving energizing power for said electro-magnetic means including switch closure means, and an armature disposed adjacent the electro-magnetic means and having manually operable means for initiating movement of said armature and means for closing said closure switch means to cause energization of said electro-magnetic means, another armature, said armatures being disposed respectively adjacent opposite end poles of the electro-magnetic means, biasing means for urging each armature away from the electro-magnetic means, said another armature having one end extending toward and for blocking movement of the first armature and another end engaging and assisting movement of the one armature manually operable means.
Claim 2
Dependent Claim
118 words
A relay construction comprising; electro-magnetic means having opposite end poles, means coupling to said electro-magnetic means for receiving energizing power for said electro-magnetic means including switch closure means, and an armature disposed adjacent the electro-magnetic means and having manually operable means for initiating movement of said armature and means for closing said closure switch means to cause energization of said electro-magnetic means, another armature, said armatures being disposed respectively adjacent opposite end poles of the electro-magnetic means, biasing means for urging each armature away from the electro-magnetic means, said another armature having one end extending toward and for blocking movement of the first armature and another end engaging and assisting movement of the one armature manually operable means.
Claim 3
Dependent Claim
18 words
A relay construction as set forth in claim 1 including another switch closure means coupled to said armature.
Claim 4
Dependent Claim
147 words
A relay construction comprising; electromagnetic means having opposite end poles, circuit means including means for receiving input power and contact closure means in series between the input power receiving means and the electromagnetic means, first armature means carrying manual switch means and including a first armature and means pivotally supporting the first armature adjacent one end of the electromagnetic means, said first armature mans further including means engaging the contact closure means upon operation of said switch means to couple input power to said electromagnetic means, second armature means including a second armature and means pivotally supporting the second armature adjacent the other end of the electromagnetic means, said second armature means having a first leg responsive to the position of the second armature for blocking the movement of the first armature in a first position and enabling movement of the first armature in a second position.
Claim 5
Dependent Claim
147 words
A relay construction comprising; electromagnetic means having opposite end poles, circuit means including means for receiving input power and contact closure means in series between the input power receiving means and the electromagnetic means, first armature means carrying manual switch means and including a first armature and means pivotally supporting the first armature adjacent one end of the electromagnetic means, said first armature mans further including means engaging the contact closure means upon operation of said switch means to couple input power to said electromagnetic means, second armature means including a second armature and means pivotally supporting the second armature adjacent the other end of the electromagnetic means, said second armature means having a first leg responsive to the position of the second armature for blocking the movement of the first armature in a first position and enabling movement of the first armature in a second position.
Claim 6
Dependent Claim
40 words
A relay construction as set forth in claim 3 including said second armature means having a second leg responsive to the position of the second armature and engaging a section of the first armature means to assist in switch action.
Claim 7
Dependent Claim
51 words
A relay construction as set forth in claim 4 wherein said electromagnetic means also has opposite sides with the first leg extending along one side to block the first armature and the second leg extending along the other side to engage the manual switch means part of the first armature means.
