Electromechanical relay

Claim 2

An electromechanical relay which comprises: a. a base member having a compartment; b. a electromagnetic coil subassembly positioned in the compartment; c. an armature subassembly pivotally mounted on top of said electromagnetic coil subassembly, said armature subassembly having camming means thereon; d. a plurality of contact members having legs thereon extending down and below said base member and having a plurality of arms extending across said compartment from either side, said arms including, i. first arm providing a first fixed contact describing a generally rectangular path, ii. second arm providing a second fixed contact positioned alongside the first fixed contact and electrically isolated therefrom, iii. a third arm providing a movable arm and positioned opposite said fixed contacts, the end of said third arm being bifurcated into two movable contacts with one such contact overlapping said second fixed contact and the other such contact being off-set and downwardly displaced and underlying said first fixed contact; iv. a fourth arm adapted to provide a current path to said electromagnetic coil whereby when said coil is energized, magnetic force causes said armature subassembly to rotate about with said camming means engaging said third arm and moving it from one fixed contact to another fixed contact; and e. insulating cover means for covering said compartment.

Claim 3

An electromechanical relay which comprises: a. a insulating housing having a compartment therein, b. means for switching an electrical current back and forth from one circuit to another, said means including a plurality of contact members of which, i. a first member includes an arm fixed in space over the compartment, said arm providing a first fixed contact, ii. a second member includes an arm fixed in space over the compartment and positioned generally parallel to the arm of the first member, said arm of the second member providing a second fixed contAct, iii. a third member, located on the opposite side of the compartment from the first and second members, includes a movable arm extending across the compartment and providing a movable contact, the end of said arm being formed into two spaced-apart parallel fingers with the first finger being the axially extension of the arm and the second finger being offset laterally and displaced downwardly relative to the arm, the first finger overlapping and engageable with the first fixed contact and the second finger underlapping and engageable with the second fixed contact, and iv. a fourth member includes a arm adapted to provide an electrical path to a coil, all of the aforementioned contact members each having as an integral part thereof, a leg which extends alongside the housing and depends therefrom, said legs adapted for insertion into printed circuit board receptacles for engagement with electrical circuits thereon; and c. an electromagnetic coil operating an armature pivotally mounted on top thereof, said coil positioned in the compartment beneath the contact members with the armature engageable with the movable contact so that as the coil is energized the armature moves the movable contact removing one finger from one fixed contact and engaging the other finger to the other fixed contact and thereby switching an electrical current which may pass through said contact members from one fixed contact to the other.

Claim 4

An electromechanical relay which comprises: a. a insulating housing having a compartment therein, b. means for switching an electrical current back and forth from one circuit to another, said means including a plurality of contact members of which, i. a first member includes an arm fixed in space over the compartment, said arm providing a first fixed contact, ii. a second member includes an arm fixed in space over the compartment and positioned generally parallel to the arm of the first member, said arm of the second member providing a second fixed contAct, iii. a third member, located on the opposite side of the compartment from the first and second members, includes a movable arm extending across the compartment and providing a movable contact, the end of said arm being formed into two spaced-apart parallel fingers with the first finger being the axially extension of the arm and the second finger being offset laterally and displaced downwardly relative to the arm, the first finger overlapping and engageable with the first fixed contact and the second finger underlapping and engageable with the second fixed contact, and iv. a fourth member includes a arm adapted to provide an electrical path to a coil, all of the aforementioned contact members each having as an integral part thereof, a leg which extends alongside the housing and depends therefrom, said legs adapted for insertion into printed circuit board receptacles for engagement with electrical circuits thereon; and c. an electromagnetic coil operating an armature pivotally mounted on top thereof, said coil positioned in the compartment beneath the contact members with the armature engageable with the movable contact so that as the coil is energized the armature moves the movable contact removing one finger from one fixed contact and engaging the other finger to the other fixed contact and thereby switching an electrical current which may pass through said contact members from one fixed contact to the other.
