An essential component for the safe and convenient operation of whirlpool tubs, this device provides a means of remotely activating and deactivating the pump motor. It typically consists of a button, a length of flexible tubing, and a pressure switch. The button, often located on the tub deck or surrounding surface, when pressed, sends a pulse of air through the tubing to the pressure switch, which in turn controls the electrical circuit powering the pump. This system offers electrical isolation, eliminating the risk of electric shock associated with direct electrical switches near water.
The benefit of utilizing such a system lies primarily in enhanced safety. Because the switch itself is pneumatically operated, there’s no direct electrical connection at the point of user interaction. This design has become a standard safety feature in whirlpool tubs, greatly minimizing the potential for electrical hazards. Its development reflects an industry-wide commitment to improve the safety and usability of these fixtures. The readily availability of replacement parts and complete assemblies ensures that tubs can be easily repaired and maintained, extending their lifespan.
