    Abstract: A spring-charging handle of the mechanism is turned in one direction to charge a closing spring for the switch blades and in an opposite direction to charge an opening spring. Either spring may be charged first, but both springs must be charged before the closing spring can be discharged to close the switch blades. An interlock is provided between a door for enclosing the switch mechanism and a latch releasing means.

    Abstract: The mounting means includes a pair of aligned generally U-shaped spring members, a generally U-shaped mounting member disposed within the spring members, and a generally L-shaped mounting member having one leg dividing the space between the legs of the U-shaped mounting member and the other leg secured to the bight portion of the U-shaped mounting member. A flat switch blade is pivotally mounted on one side of the dividing leg and a flat blade terminal of a fuse is receivable on the other side of the dividing leg of the L-shaped mounting member.

    Abstract: The switch enclosure comprises a box within which a switchoperating mechanism is mounted. An external operating handle is operable to cause the mechanism to move to ON and OFF switch positions. The box is closed by a hinged door, and a sealing gasket is provided between the door and box. A combined sealing and latching bar in the box is arranged to draw the door into, and hold it in, closed sealing engagement. The invention is characterized in that a ratchet connection is provided between the switch-operating mechanism and the bar for moving the bar into sealing and latching position when the handle is operated to move the switch-operating mechanism a predetermined distance toward ON position and to release the mechanism from the bar, and permit return of the mechanism to OFF position by the handle, while the bar remains in sealing and latching position. An interlock on the door latches the bar in the sealing and latching position upon movement of the bar into said position by the mechanism.
