ABSTRACT:
Apparatus for controlling parallel connected unequal electrical loads, such as the speeds of a two speed motor, from a two wire branch circuit having one leg load connected through a single pole, single throw switch, utilizing the unbalanced characteristics of the different loads, such as the high and low speed windings of a two speed split phase motor after the start winding circuit is broken, to control multiple solid state static switches coupled through a flip-flop for sequentially controlling the loads.
