A relay includes a housing, an electric contact system in the housing, an electromagnetic system in the housing, and a magnetic blowing arc-extinguish device. The electric contact system includes a static contact with a static contact portion and a movable contact with a movable contact portion. The electromagnetic system is configured to drive the movable contact to move between a closed position in which the movable contact is in electrical contact with the static contact and an opened position in which the movable contact is separated from the static contact. The magnetic blowing arc-extinguish device includes a permanent magnet statically provided near the static contact and configured to lengthen an electric arc between the static contact portion and the movable contact portion by an electromagnetic force to extinguish the electric arc.

The present invention relates to a molded-case circuit breaker with a main contact interlock feature preventing improper operation of a tripping mechanism that trips main contacts when the main contacts fuse together. The circuit breaker includes a handle that transfers the user's operational force; a switch lever rotatably mounted on a side plate and connected to the handle, with a pressure portion formed on a part of it; a shaft link, one end of which is rotatably mounted on a shaft pin, that has a contact region on the top; a trip lever rotatably mounted on the side plate, one end of which is slidably connected to the shaft link, and the other end of which is connected to a nail of a tripping mechanism, wherein, if the pressure portion makes contact with the contact region, the trip lever rotates the nail.

The present invention relates to a vehicle control panel comprising a switch cap comprising electrical connection pads arranged on a side of the switch cap, and an electric circuit printed on an inside surface of the switch cap associated with selecting a state of the function. A panel member has an opening in which the switch cap is pivotally and releasably attached. The panel member has electrical circuit closing members attached on an inner surface of the panel member. Pairs of the electrical connection pads are adapted to coincide and make contact with a respective one of the electrical circuit closing members to close an electric circuit portion in the switch cap such that an external electrical circuitry operates the function.

Electrical switch contact sets are disclosed. A disclosed example apparatus includes a movable platform having first and second contacts, where the first and second contacts electrically coupled via the movable platform, and a stationary portion having third and fourth contacts, where the movable platform is movable to bring the first and second contacts in contact with the third and fourth contacts, respectively, to simultaneously close a current path of an electrical circuit associated with the first, second, third and fourth contacts.

An electrical switch. The electrical switch comprises at least one fixed contact, a movable contact contacting the fixed contact, and at least one extinguishing apparatus positioned after the fixed contact in an opening direction of the movable contact. A permanent magnet is further positioned after the extinguishing apparatus in the opening direction of the movable contact.

An electrical switch. The electrical switch includes at least one fixed contact and a movable contact contacting the fixed contact. At least one shutter element is arranged to move in synchronism with the movable contact. The shutter element is positioned in an extended position between the fixed contact and the movable contact and in a contracted position outside the patch of the movable contact allowing the movable contact to turn from the open position to the closed position.

A fusible disconnect switch devices includes dual sets of switch contacts to connect or disconnect a current path through an overcurrent protection fuse with reduced arcing severity. Faster acting and longer contact path switch mechanisms are described providing satisfactory switching of DC circuits without excessive electrical arcing in a reduced physical package size.

A switching system, in particular of an on-board electrical system of a motor vehicle having a first disc which has a first, a second, a third, and a fourth stationary contact. The second and the third stationary contact, are electrically contacted by a first contact bar of the first disc. The switching system also has a second disc which has a first, a second, a third, and a fourth movable contact. The first and the second movable contact are electrically contacted by a second contact bar of the second disc, and the third and the fourth movable contact are electrically contacted by a third contact bar of the second disc. The second disc is rotationally mounted about a rotational axis relative to the first disc, wherein all the contacts are electrically connected in series in an angular position. A circuit breaker is also provided that includes a switching system.

A switching device for LV electric installations is disclosed which can include an outer casing and one or more electric poles. Each electric pole can include one or more mobile contacts and one or more fixed contacts adapted to be coupled or uncoupled. A mobile contact assembly is operatively coupled with the mobile contacts such that the mobile contacts move together with the mobile contact assembly. The mobile contact assembly is adapted to reversibly move between a first contact position, in which the movable contacts and the fixed contacts are coupled and a second contact position, in which the movable contacts and the fixed contacts are uncoupled. A mechanical control assembly is provided for operating said mobile contact assembly.

An electrical switching assembly. The electrical switching assembly includes an integral handle and rotor unit including an integral rotor portion and a handle portion. The rotor portion is configured to receive one or more conductors and is configured to be received in a line base. The integral handle and rotor unit includes the handle portion and the rotor portion in a one-piece assembly and the integral handle and rotor unit is molded as a single unit and formed from a single rigid insulating material.
