TOUCHSTONE electronics operate every luxury bath feature while reducing costs, complexity, and production time. Manufacturers that have to inventory and switch out controllers for each of their bathtub models face increased expense, production time, and chance of error. With TOUCHSTONE®, there’s no need for stocking and swapping multiple types of controllers. Choose features right from your production line. Customize our feature-rich controllers right from the production line with one-of-a-kind "selection software." TOUCHSTONE accommodates dozens of features, like single and multi-speed, LEDs, and timers. TOUCHSTONE is the only one-box system powered by a single NEMA cord. The controller takes two loads totaling 15 or 20 amps, plus LED lights, with no messy wiring required.
