ABSTRACT:
This relates to a rotary switch and rotary valve assembly for a multiple work station machine wherein the work stations rotate and are sequentially presented to an operating position. There may be a high voltage and two low voltage switches with the switches being so constructed wherein electrical connections are made with each work station in timed relation to its presentation to the work position and for the required period of time. Further, the rotary valve assembly functions in sequence to present operating fluids to each work station in the order of presentation of such work station to its operating position and in timed sequence to the operation performed thereby.
