摘要： A DC relay capable of extinguishing arc and resisting short-circuit current includes two stationary contact leading-out terminals, a push rod component, a straight sheet type movable spring mounted on the push rod component and two permanent magnets. The magnetic poles on the sides opposite to each other of the two permanent magnets are opposite. Two permanent magnets are connected to two yoke clips including at least two yoke sections on two sides in the width direction of the movable spring corresponding to the movable and stationary contacts. Upper magnetizers are mounted above the position. The lower magnetizers are mounted under the position. The upper and lower magnetizers can approach or come into contact with each other through the through holes in the movable spring. At least two independent magnetically conductive loops are formed in the width direction of the movable spring by the upper and lower magnetizers.

摘要： An electromagnetic relay includes a fixed terminal, a base, a fixed contact, a movable contact, a movable contact piece, and a movable terminal. The base supports the fixed terminal. The fixed contact is connected to the fixed terminal. The movable contact faces the fixed contact. The movable contact is connected to the movable contact piece. The movable terminal is provided separately from the movable contact piece and supported by the base. The movable terminal includes a support portion. The support portion is connected to the movable contact piece below the movable contact and supports the movable contact piece. The support portion includes an upper edge and a recess. The recess has a shape recessed downward from the upper edge at a position overlapping the movable contact piece.

摘要： A DC relay capable of extinguishing arc and resisting short-circuit current includes two stationary contact leading-out terminals, a push rod component, a straight sheet type movable spring mounted on the push rod component and two permanent magnets. Two permanent magnets are respectively arranged on two sides in the width direction of the movable spring. two permanent magnets have same magnetic poles on a side facing to the movable and stationary contacts; and a yoke clip is connected between the two permanent magnets. Upper magnetizers are mounted above the position. The lower magnetizers are mounted under the position. The upper and lower magnetizers can approach or come into contact with each other through the through holes in the movable spring.

摘要： A mobile contact-holder for a cutout includes a support in which there is formed a housing, a mobile element made of electrically conductive material mounted to slide, in a longitudinal axis of the support, in the housing of the support, an upstream electrical contact pad and a downstream electrical contact pad borne by the mobile element and a spring which exerts a return force on the mobile element. The support includes two oblong holes emerging in the housing and extending along its longitudinal axis. The mobile contact-holder also includes a guiding shaft which is fixed in translation with respect to the mobile element, which extends along an axis parallel to a transverse axis of the support and which is engaged in the oblong holes of the support. The guiding shaft engaged in the oblong holes guides the translation of the mobile element in the housing.

摘要： Provided is a terminal of a relay, by which defective sealing in the relay can be prevented. A movable terminal of the relay has: a first plate including a first inner surface, a first outer surface opposed to the first inner surface, and a first through opening which opens to the first inner surface and the first outer surface; a second plate including a second inner surface, a second outer surface opposed to the second inner surface, and a second through opening which opens to the second inner surface and the second outer surface; and a folded part which connects the first plate to the second plate. The first through opening is partially overlapped with the second through opening, and the second inner surface is partially exposed to the first through opening.

摘要： 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.

摘要： An electromechanical switch includes a housing, first and second stationary contacts mounted to the housing, a movable contact, and a carrier sub-assembly. The housing has a divider wall. The carrier sub-assembly includes a support rod that extends through an aperture in the divider wall and is coupled to the movable contact. The carrier sub-assembly is configured to move the movable contact relative to the first and second stationary contacts. The carrier sub-assembly includes a contact spring surrounding the support rod between the divider wall and the movable contact. The carrier sub-assembly also includes a dampener in engagement with the contact spring. The dampener is configured to absorb vibration along one or more of the contact spring or the movable contact.
