Locking arrangement for disconnect switch

A locking arrangement for a disconnect linkage that operates an electrical switch between closed and opened positions and that is movable between closed and opened positions along a predetermined path, the locking arrangement comprising a first member extending from and carried by the disconnect linkage and first means carrying a second member and being interconnected with the disconnect linkage so as to be movable in response to movement of the disconnect linkage for defining movement of said second member into an aligned position with said first member when the disconnect linkage is in an opened position and for defining movement of said second member away from said first member when the disconnect linkage is moved out of the opened position and toward a closed position.

A locking arrangement for an electrical switch that includes a disconnect linkage movable between closed and opened positions along a predetermined path, the locking arrangement comprising:

• a first locking member carried by the disconnect linkage so as to be movable therewith between predetermined positions corresponding to the closed and opened positions of the disconnect linkage;
• and
• means movable in response to movement of the disconnect linkage and including a second locking member for moving said second locking member to a predetermined position when the disconnect linkage is moved to the opened position and for moving said second locking member out of said predetermined position when the disconnect linkage is moved out of the opened position, said first locking member and said second locking member being aligned in predetermined relationship when the disconnect linkage is in the opened position, said moving means comprising support means for providing a pivotal support with respect to the disconnect linkage and means extending from said support means and being pivotally connected to the disconnect linkage.
