Abstract
A double break disconnect switch including a bearing arrangement carrying a switch blade assembly is mounted on a drive arrangement. The switch blade assembly is rotatable longitudinally during initial opening and final closing of the switch and transversely for final opening and initial closing. The switch blade assembly is hinged for rotation about a hinge axis offset from the center of gravity of the switch blade for initial opening and for final closing. A blade bearing is provided of very small in diameter. The drive assembly uses the weight of the blade to keep the blade from rotating longitudinally and uses a cam arrangement including a roller riding in a slot of a blade drive plate that is spring loaded on one end and pivotally attached at the other end to rotate the blade longitudinally providing greater force to rotate the blade as contacts engage.
