The Crystal Fountains ChoreoSwitch is a water level independent sequencing nozzle assembly that produces programmed effects at high switching speeds, up to 10 times per second, when receiving a signal from a programmable logic controller. Grouped together, multiple ChoreoSwitches can produce a wide variety of geometric patterns such as spirals, tilting pates, alpha-numeric characters and travelling waves. Varying heights can be produced using a variable speed drive pump. The ChoreoSwitch is a low maintenance device that produces no water hammer.
