摘要： An electrical switch, including an insulation base, an insulative-and-movable component, at least two output ports, and at least two transmission ports, is provided. The insulative-and-movable component is disposed on the insulation base and is adapted to operate between at least two switch positions relative to the insulation base. The two output ports are disposed on the insulation base. The two transmission ports are disposed on the insulative-and-movable component. When the insulative-and-movable component is located at one of the two switch positions, one of the two output ports is aligned with one of the two transmission ports and other one of the two output ports is misaligned with other one of the two transmission ports.

摘要： The present invention relates to an air circuit breaker, in which a recess is formed on one side or each of both sides of each contact plate provided in an insulating cage so as to reduce a contact area between a movable contactor and the contact plate when the movable contactor and the contact plate are brought into contact with each other, thereby preventing a contact portion between the movable contactor and the contact plate from being melted due to heat generation.

摘要： The invention relates to a single- or multi-pole switching device, in particular for DC applications, having at least one rotating switching element (2) which is connected to a drive, and also comprising switching contacts (4, 5), connection pieces (7) and connection poles or connection terminals (8) and a housing arrangement which accommodates the abovementioned parts. According to the invention, a movably guided rotary cylinder (2) is formed in the housing arrangement, said rotary cylinder being located in a body which is designed as a rotary cylinder holder (1). The rotary cylinder (2) has at least one contact pin (3) which passes radially or tangentially or eccentrically through the rotary cylinder and has, at its end, a contact piece (4) in each case. Mating contact pieces (5) are arranged in the rotary cylinder holder (1), said mating contact pieces being electrically connected to the connection pieces (7) or connection poles or connection terminals (8). A narrow, arc-influencing gap is present between the rotary cylinder (2) and the rotary cylinder holder (1), wherein, as a result of the movement of the rotary cylinder (2), the electrical connection between the contact pieces (4) and the mating contact pieces (5) can be broken by way of the contact pin (3) and the resulting disconnection arcs (11) enter the air gap subject to an extension and are rapidly extinguished there.

摘要： A breaker includes conductors, each including an elongated flat cut portion, cutting chambers arranged in correspondence with the cut portions, a single cutting member that includes blades to cut the cut portions in the cutting chambers, a gas generator that generates gas to move the cutting member toward the cut portions, and an arc attenuation portion located between the two cut portions that are adjacent to each other. The conductors are located between two devices. Each cut portion is cut to form two separated cutting ends and electrically disconnect the devices. The arc attenuation portion attenuates an arc generated between the two cutting ends of one of the two adjacent cut portions and the two cutting ends of the other cut portion.

摘要： A switching apparatus wherein the life and the reliability of an electric contact are improved by fundamentally suppressing formation of black powder and activation of the surface of the contact by a chemical reaction. Microcapsules in which organic acid or organic acid precursor from which organic acid is produced as time passes is enclosed are placed into the internal space of an enclosed case so that organic compounds produced on and in the proximity of contact surfaces is oxidized with organic acid which escapes from the microcapsules and vaporized in the enclosed case without forming a film on the surfaces of the contacts to suppress activation of the surfaces of the contacts.

摘要： An electrical switch (1) is proposed which consists of a lower housing component (3) and an upper housing component (2). In receptacles (24) of the lower housing component (3) contact lugs (23', 23") with a normally closed contact (29', 29") are arranged. In the upper housing component (2) a contact element with a switching contact (22) is arranged. The contact element is moved, via a pressure spring (17) and a slider rod (9) to which an actuation element (5) is coupled, so as to flip between the off-position and on-position. At the contact lug (23') which is arranged on the side of the lower housing component (3) facing away from the contact element in the off-position, an arc extinction lug (32) which consists of an extension is attached to the normally closed contact (29').

摘要： A circuit breaker includes an arc shearing plate which is driven to thrust between a pair of contacts being separated so as to shear an arc formed therebetween for rapid arc extinction. Included in the circuit breaker is an over-current responsive actuating member which applies an impact to one of the contacts for rapid contact separation in response to a predetermined over-current condition such as caused by a short-circuit. The actuating member is also coupled to the arc shearing plate so as to control the thrusting movement of the arc shearing plate in synchronism with the rapid contact separation, whereby the timing of inserting the plate between the contacts can be easily controlled with respect to that of separating the contacts for achieving rapid arc extinction and providing a high arc voltage and current limiting action.
