    摘要： A high voltage, high current, switching device includes a jaw assembly electrically connected to a first electrical conductor, a housing assembly electrically connected to a second electrical conductor and a blade assembly fixedly attached to the housing assembly at a first end thereof. The blade assembly has an electrically conductive blade contact fixedly attached to a second end distal from the first end. Further, the housing assembly and the blade assembly pivot about a first axis to drive the blade contact into the jaw assembly to close the switch and the blade assembly is operable to rotate about a second axis perpendicular to the first axis only when the distal end of the blade assembly is seated in the jaw assembly. Thus, the blade does not pivot about its longitudinal axis prematurely, for example, before it is properly seated in the electrical terminal.

    摘要： An air-insulated high-voltage disconnector including a pivotally-mounted arm suitable for pivoting at one of its ends about a horizontal axis that is perpendicular to the axis null of the arm, and also suitable for turning about its own axis null, the free end of the arm carrying a contact part or nullhammernull which, when the disconnector is in the closed position, co-operates with a jaw comprising a jaw support to which two facing rows of contact fingers are fixed, wherein the hammer is equipped with contact tabs co-operating with the contact fingers, each contact tab forming a wedge of angle null, which wedge acts, during disconnector closure, to meet the corresponding row of fingers with an angle of attack null, said angle of attack null being less than 90null.

    摘要： The invention provides an improved positive latch for high voltage, air break disconnect switches of the type having an elongated blade with one end swiveling on a terminal to switch its opposite end from the remote terminal, the blade being rotatable about its longitudinal axis and relative to the terminals and provided at its switching end with a transversely projecting contact lug shiftable by rotation of the blade into and out of frictional engagement with the remote terminal. The latch is pivotally mounted on the remote terminal and has a hook-like portion spring biased downwardly into latching position with respect to the end portion of the blade and is rotatable out of latching position by engagement with the latch of an arm carried by the blade when the contact lug is rotated out of engagement with the remote terminal and is formed with an extension engageable with the blade mounted latch operating arm for opening the latch as the blade approaches closed position.

    摘要： A high voltage switch assembly including a base, elongated insulators mounted on and diverging from the base, with the insulators occupying a common vertical plane, and a switch mounted adjacent the ends of the insulators which are remote from the base. The switch includes a blade pivoted for swinging in the common plane of the insulators. One of the insulators in the assembly is supported for rotation about its longitudinal axis, and is interconnected with the blade in such a fashion that rotation of the insulator produces swinging of the blade.
