Cal Spas SwitchlessPro™ Motors feature low and high speeds with exclusive switchless technology. The low speed is used for filtration and heating while the high speed is used for creating a pressurized massage. Instead of a mechanical switch with springs that physically change between low and high speeds, Cal Spas spa motors are switchless and use an electrical relay that provides resiliency and protects the motor. Each switchless pump has a 50% thicker and longer shaft than standard motors for increased durability and output. Hot tub owners will experience a 50% increase in energy efficiency during filtration mode since the motors are able to fully operate at only two amps.
