Electromagnetic relay
An electromagnetic relay includes a movable element, a movable yoke, a fixed yoke, a movable section, and a stopper. The movable element includes a movable contact point. The movable yoke is connected to the movable element to move together with the movable element. The movable section includes a movable core made of an inorganic magnetic material and a shaft made of an inorganic material. The fixed yoke is made of an inorganic magnetic material and disposed between the movable core and the movable yoke. The stopper protrudes from either one of the fixed yoke or the movable section toward the other to contact with the other when the movable section moves toward the fixed yoke. The stopper is integrally formed with the either one of the fixed yoke or the movable section.
SYSTEMS AND METHODS FOR CONTROLLING A POSITION OF CONTACTS IN A RELAY DEVICE
A system may include a relay device. The relay device may include an armature that moves between a first position that electrically couples a first contact to a second contact and a second position that electrically uncouples the first contact from the second contact. The relay device may also include a relay coil that receives a voltage configured to magnetize a relay coil, thereby causing the armature to move from the first position to the second position. The system also includes a control system that receives an indication that the armature is in the second position and sends a signal to an actuator in response to receiving the indication. The signal causes an arm associated with the actuator to move the armature to achieve a gap distance between the first contact and the second contact.
Closing spring assemblies for electrical switching devices
A closing spring assembly for an electrical switching device is provided. The closing spring assembly is configured to exert a closing force on a moving contact of the switching device. The closing force helps to maintain physical and electrical contact between the moving contact and an associated stationary contact, so that the moving and stationary contacts form a path for conducing electric current through the switching device. The closing spring assembly is configured so that the closing force remains constant or decreases as the moving contact is driven away from the stationary contact during switching of the current path away from the moving and stationary contacts.

Accelerated motion relay
An electrical relay (2) includes an electromagnetic drive system for providing bi-directional drive. The electrical relay (2) includes a first a coil (212) and a second coil (213). A current is supplied to the coils (212) and (213) in opposite directions. The two coils (212) and (213) can be used to accelerate the armature in either direction in relation to the two contacts. This can be used to drive the armature to either one of the contacts and to accelerate and decelerate the armature during a single transit. In the latter regard, the armature can be accelerated and decelerated to shorten the transit time, reduce bounce, reduce wear on the contacts, and allow for different contact material options.
