Abstract: A resistance assembly having a resistance member prevents accidental movement of a hookstick operated switching assembly. A switch assembly of the hookstick operated switching assembly is mounted on a base. The resistance member includes a lever connected to the switch assembly that moves the switch between opened and closed positions. A first end of a pin is connected to the lever. A resistance member is connected to a second end of the pin. The resistance member contacts the base when the lever rotates to move the switch assembly between open and closed positions, thereby preventing accidental opening and closing of the switch assembly.

The first and second positions of the pivot member and each of the closed and open positions of the fuseholder, correspond to each of the non-release and release positions of the lever member.

Abstract: A hookstick operated switch assembly includes a switch mounted to a support and movable between open and closed positions. An operating lever is connected to the switch for opening and closing the switch. A locking arm is positioned proximal the switch. A locking member is receivable by the locking arm when the switch is in the open position to prevent movement of the operating lever, thereby locking the switch in the open position.

Abstract: Improved switchblade-type, air dielectric switchgear apparatus is provided which utilizes a minimum of supporting insulators and incorporates readily field-replaceable bushing assemblies so that the switchgear apparatus may be serviced in the field using only conventional tools. In preferred forms, the switchgear apparatus includes internal switch assemblies making use of substantially vertically oriented switchblades mounted for pivotal movement about an elevated, generally horizontal axis located above the corresponding stationary contacts. The replaceable bushing assemblies are advantageously mounted at a level for interconnection with the upper ends of associated switchblades, and the assemblies include a conical outermost connection and adapted to receive a line connecting elbow, together with an elongated, inwardly extending, electrically conductive intermediate portion carrying an innermost terminal.

Abstract: Improved blade-type, air dielectric switchgear apparatus is provided having spring loaded, fast acting, operator independent mechanism for selective opening and closing of internal switch contacts. Preferably, the operating mechanism includes a pair of opposed, pivotal, notched, scissor-like arms with a rotatable latch plate therebetween; a pair of latching pins are carried by the plate, and the latter is operably connected with a power spring assembly. A trip element is also provided which, upon rotation thereof in either a clockwise or counterclockwise direction, serves to shift a corresponding arm away from the latch plate to disengage the latching components. At this point a high velocity rotational movement is imparted to the latch plate by the spring assembly to rotate the latch plate to a second position wherein the plate and the opposed arm come into latching engagement.
