Abstract
An improved disconnecting switch is provided having an improved hinging structure which provides the traditional movements of a vertical break disconnect switch-blade in a simple and unique way. The switch-blade rotates about its longitudinal axis on a blade plug which is supported by a hinge pin that passes at a right angle through slots provided in the blade and a hole in the blade plug. The slots define the amount of rotation and prevent the switch-blade from sliding along the longitudinal axis. The structure also allows the switch-blade to pivot open on the axis of the hinge pin. The switch-blade contact on the hinge end of the switch may be used as the supporting member for the hinge pin.
