In case of using multi-contacts or flat braided wires for constituting a current carrying structure of a movable part in a vacuum relay, problems tend to appear, which are enlargement of a control mechanism, complication, increased operation force and the like. The vacuum relay 1 includes an insulating cylinder 2, a first relay connecting portion 4 that is connected to one open end of the insulating cylinder 2 and has on its inner surface a first contact 3, a second relay connecting portion 5 that is arranged in the insulating cylinder 2 to face the first relay connecting portion 4, a movable member 7 that is movably arranged between the first and second relay connecting portions 4 and 5 and has a second contact that is brought into contact with the first contact when the movable member is moved toward the first relay connecting portion, and a control mechanism 8 that moves the movable member 7 in both directions to establish and break the contact between the two contacts. Between the movable member 7 and the second relay connecting portion 5, there is provided a bellows 11 through which the movable member 7 and the second relay connecting portion 5 are electrically connected.

A system for a laminated buswork with flexible conductors for an electric aircraft is presented. The system includes a plurality of electrical devices and an electrical bridging device electrically connected to each electrical device of the plurality of devices.

A shunt tab assembly is for an electrical switching apparatus, such as a circuit breaker. The electrical switching apparatus includes a housing, separable contacts enclosed by the housing, an operating mechanism for opening and closing the separable contacts, and a number of shunts. The operating mechanism includes a trip unit. The shunt tab assembly includes a shunt tab structured to be electrically connected to the shunts, a biasing element structured to bias the shunt tab toward a predetermined position with respect to the housing, and a fastener structured to mechanically couple and electrically connect the trip unit to the shunt tab.

A movable contact assembly for an electrical switching apparatus is provided. The movable contact assembly includes a number of shunts, and, a carriage assembly including two sidewalls and a contact arm assembly. The carriage assembly sidewalls are disposed in a spaced relation. The contact arm assembly includes a plurality of contact arms, a number of isolation members, a number of movable contacts, and an axle. Each contact arm defines an opening. One movable contact is disposed on each contact arm. Each contact arm is rotatably coupled to the axle with the axle extending through the contact arm opening. Each isolation member is disposed adjacent at least one contact arm. Each isolation member is coupled to, and in electrical communication with the adjacent contact arm. The shunts are coupled to, and in electrical communication with, the isolation members. In this configuration, no shunt operatively engages a contact arm.

A key structure includes a circuit board, a housing, a first metallic element, a second metallic element, a keycap and a conductive strip. The conductive strip is disposed within the housing. The first metallic element and the second metallic element are electrically connected with the circuit board. The housing is disposed on the circuit board. The keycap is fixed on the housing. While the keycap is depressed, a first end of the conductive strip is pressed by the triggering part and the conductive strip is swung relative to the housing. Moreover, a second end of the conductive strip collides with the second metallic element. Consequently, the key structure is triggered. When the second end of the conductive strip collides with the second metallic element, a click sound is generated.

Some embodiments of the present disclosure relate to a relay capable of preventing a chattering phenomenon, and capable of solving an unbalanced contact state occurring when contacts come in contact with each other. The relay may include: a stationary contact having a first stationary contact and a second stationary contact; a movable contact moveable to a first position to contact the first stationary contact, and a second position to be separated from the first stationary contact; a conductive connector configured to always electrically connect the movable contact with the second stationary contact; and a driving mechanism configured to provide a driving force to the movable contact such that the movable contact is moveable to the first position or the second position.

An improved connection apparatus that meets these and other needs includes, in one embodiment, an approximately J-shaped flexible conductor having at its end an opening that receives therethrough a portion of the shank for mechanical and electrical connection therebetween. The conductor further includes a hole formed therein at approximately its midpoint that receives therein, in a movable and non-contacting fashion, another portion of the elongated shank. In another pair of embodiments, another connection apparatus includes a flexible conductor that is co-formed with a rigid conductor to form a single piece unitary element. The free end of the flexible conductor is connected with the movable shank, and the rigid conductor is connectable with the primary conductor of the circuit. By providing the flexible conductor and the rigid conductor as a co-formed unit, a detachable fastener need not be employed to provide a connection therebetween, which reduces heat generation.
