My homework is due Tues and I am haveing a hard time "drawing" Designing a circuit where a low float switch turns on one of two motors, alternating the starts between the two motors to equalize run time. the motor not running is always on stand by so if the currently operating motor is disabled for any reason the backup motor will automatically start. also add a high level float switch that will turn on both motors when ever a high demand is called for. each motor is a 25 hp 3phase 480 vac class c, the control circuit is a 120 vac

 

I had to look up what a float switch was. I am thinking of a floating potential. Do you need a schematic or a hand drawn circuit?
