ABSTRACT:
A group operated circuit disconnect apparatus for overhead electric power lines has a base in the form of a box-like housing which mounts on a pole, an upright shaft extends through the housing, and a transverse shaft also extends through the housing. A linkage is mounted on the shafts in the housing so that axial rotation of the upright shaft axially rotates the transverse shaft, and this causes three circuit disconnect switches mounted on the housing to be moved simultaneously between closed positions and open positions, or vice versa, as the upright shaft is manually rotated. An end of the housing has a removable closure plate for access to the linkage.
