Abstract: An electrical switching device that includes first and second circuit assemblies. Each of the first and second circuit assemblies includes a base terminal and a moveable terminal that is configured to flex to and from the base terminal. The switching device also includes a coupling element that is operatively coupled to the moveable terminals of the first and second circuit assemblies. The switching device also includes an electromechanical motor that has a pivot body that is operatively coupled to the coupling element. The pivot body is configured to rotate bi-directionally about a center of rotation. The pivot body moves the coupling element side-to-side along a longitudinal axis so that the moveable terminals move in a common direction with respect to each other and along the longitudinal axis when the pivot body is rotated between first and second rotational positions.

Abstract: The invention is directed to a switch assembly which can be used in situation in which the switch accommodates the flow of high voltage current. An actuator assembly with moveable contacts is moved by a motor driven armature. The moveable contacts are in electrical engagement with the stationary contacts when the armature is in the first position, and the moveable contacts are spaced from the stationary contacts when the armature is in the second position. By angling the stationary contacts and moveable contacts, the linear motion of the armature causes the moveable contacts to move across the surface of the stationary contacts as the armature approaches the first position. As all of the movements of the assembly are in a direction parallel to the axis of the armature, the assembly can be manufactured and operated reliably in a relatively small space. In addition, the linear movement on the angled contact provides for a positive electrical connection even in adverse environments.

Abstract: An electromagnetic relay includes a relay coil assembly, an armature, and a contact system. The contact system includes a stationary contact assembly stationary contacts and moveable contact springs adjacent to the stationary contacts. The moveable contact springs have a projecting portion. The armature is pivotably actuated in response to an electromagnetic force generated by the relay coil to move the at least one contact spring linearly between a first position and a second position. The stationary contact assembly includes an overmold portion attached to the at least one stationary contact. The overmold portion includes a dielectric material and is bonded to the at least one stationary contact to maintain a predetermined configuration of the stationary contact relative to the at least one moveable contact spring.

Abstract: An electromagnetic relay has a relay coil, an armature, a pusher and a contact system. The armature is actuated by the relay coil, and linked to the pusher to drive the pusher to operate the contact system. A set of stationary contact springs and a set of moveable contact springs have a gap separating them. The moveable contact springs connect to the pusher and to a pivot point. The stationary springs have a notch therein adjacent to the base structure portion. The pusher movement causes the stationary contact springs and the moveable contact springs to engage or disengage, and to automatically adjust the overtravel angle of the stationary contact springs relative to the moveable contact springs by bending the stationary contact spring at the notch of the stationary contact spring.

Abstract: A socket connector is provided for electrically connecting an electromagnetic relay to a plurality of electrical wires that are terminated by a mating connector. The socket connector includes a dielectric housing having a relay mounting base and a wire connector. The relay mounting base includes at least one relay receptacle. The relay mounting base is configured to receive the electromagnetic relay thereon. A plurality of terminals is held by the housing. Each terminal includes a relay contact portion and a connector contact portion. The relay contact portion extends within the at least one relay receptacle for electrical connection with the electromagnetic relay. The connector contact portion extends within the wire connector for electrical connection to the mating connector.

Abstract: An electromagnetic relay has an overtravel adjustment to set the gap in the contact arrangement. The armature is actuated by a relay coil and linked to a pusher to drive the pusher to operate the contact system. The pusher includes a rotary dial disposed in a slot on the pusher adjacent to the armature. The rotary adjustment increases or decreases a gap of the contacts to provide an over-travel adjustment. The pusher includes bifurcated tines defining the slot for receiving an armature linkage and the rotary adjustment. The rotary adjustment includes a head and a post depending from the head. The post is disposed within the slot and the head portion in contact with the armature linkage portion. The rotary adjustment sets the distance between the forward edge and the armature to achieve the desired overtravel for the contact arrangement.

Abstract: Valve structures include a combination of spool valving and poppet valving. A spool function of the structure regulates the flow of a liquid, such as the flow of fuel to a diesel engine. A poppet function provides a low leakage in the valve in a closed or cut-off state. With this combination in a valve, spool clearance can be increased reducing the cost and precision machining/assembly of the components, because the poppet to seat closure provides the sealing function at cut-off. Included are an air-gap flux adjustment to adjust responsiveness to control current, and a force pre-load adjustment.
