Abstract: A multipole, double throw relay includes a base with a coil and armature mounted at the center of the base. A terminal block with an L-shaped cantilever contact blade is mounted on one side of the coil. The contact blade extends up and over the coil, passes through a contact blade lifter affixed onto the armature and projects between a pair of contacts associated with a contact block assembly mounted on the opposite side of the coil. Operation of the coil causes the lifter to engage and move the flexible contact blade. The lifter has a lost motion action that prevents contact flutter and provides for a more efficient switching operation.

Abstract: An electromagnetic relay which is so arranged that a plate spring having a movable contact and a fixed contact plate having a fixed contact are secured to a stopper member fixed to a heel piece for the electromagnet, with a lift pin of the plate spring being adapted to contact the moving iron, so that the pressure at the contacts and the gap between the contacts as well as the lowest working voltage are readily adjusted as desired by merely transforming the stopper member. Furthermore, since the movable contact is free from positional deviation, mutual erosion or cutting between the contacts due to uneveness of the contact surfaces arising from sparks and the like has been eliminated for positive closing or opening of the contacts.

Abstract: A relay is provided for reversing the direction of current to an electric motor and providing for dynamic breaking when power is disconnected. The contacts are cantilevered from a pivoting support driven electromagnetically. Mounted inwardly of the cantilevered contacts, are a pair of cantilevered springs. Each cantilevered spring is adjacent to, and associated with, a respective cantilevered contact. When the relay is energized, displacing one of the cantilevered contacts, a respective cantilevered spring is deflected against the cantilevered contact to provide a force additional to the force induced by the cantilevered contact support. Additionally, a fulcrum is provided for supporting pivotal movement of an armature supporting the cantilevered contacts, and which is combined with the magnetic flux path of the relay.

The relay can operate on 110 millivolt range and incorporates a pair of identical switch blades which are assembled in fixed, stacked, insulated, reverse relationship on the core under an armature suspended in biased hinged relationship from a yoke. One feature of the invention is the press-fitting of the sandwich of switch blades and insulators on the core in a fixed non-rotational relationship that insures that the spacing and attitude of the contacts remains constant and providing a wiping action at the contacts during operation making the relay suitable for handling heavier currents.

Abstract: An electromagnetic relay has an angled yoke affixed to a first end of a magnetizable coil core and extending parallel to said core to an end spaced radially adjacant an opposite end of the core. An armature is pivotally supported upon the free end of the yoke for movement toward and away from said opposite end of the core. The yoke is formed with a recess or slot in its free end which engages a lateral projection from a flange affixed about said opposite end of the core. The projection cooperates with the yoke recess to fix the free end of the yoke in lateral and radial position with respect to the core. The projection and recess align the yoke in position parallel to the core during assembly of the relay, assuring good magnetic contact beween the core and the yoke at the point of attachment. The recess and projection also reinforce the assembly against mechanical displacement of the yoke during service with consequent breaking or impairment of the magnetic circuit connection.

The counter contacts are suspended by springs on the armature.

Abstract: Two relays and a push-to-start switch are mounted together on a common frame within a common housing. The cores and coils for the devices are mounted in spaced parallel relationship on the frame. Three legs which extend from one side of the frame are supported adjacent an edge of an insulated terminal strip which latter supports the terminals, contacts, and contact arms for the devices. Two legs which extend at right angles to the first-mentioned legs and which are bent from spaces therebetween are received by slots in a base plate which is also slotted to receive portions of the terminal strip and the frame to support the same. Recesses are formed in the housing member adjacent to the base plate to allow insulated conductors to enter the housing. The recesses contain teeth that bite into the insulation over the conductors to prevent them from being moved longitudinally.
