Abstract
A plurality of individual electrical load switches each having an operating tab are so mounted and oriented that the operating tabs extend toward a central axis to define a circle substantially normal to the central axis and operate substantially in the direction of the central axis. An operating arm having ends thereof arranged to be brought into register with each operating tab at mutually exclusive angular positions is normally tilt mounted in a first direction upon a rotor that may be positioned in selected ones of a plurality of angular positions by a step motor. Upon one end of the arm being brought into register with a switch operating tab, the arm is tilted in the opposite direction to effect the operation of the operating tab with which the one end thereof is in register to place the corresponding individual electrical load switch in a selected circuit condition.
