ABSTRACT:
The apparatus includes contact blades at different elevations on a utility pole rotatable between electrical connection and disconnection positions vis-a-vis contact members. To rotate the contact blades, an electromechanical linear actuator extends a clevis and crank arm to rotate a vertically extending shaft coupled to another crank and a lever arm to rotate the insulators on which the contact blades are mounted. The linear actuators are carried by support structure high on the utility pole and, by rotating the vertical shafts, the insulators and contact blades at each phase are simultaneously rotated.
