"Install any brand disposal unit with this raised button from Westbrass. The raised button feature is easier on manicured nails, while protecting the user from electricity. Sturdily constructed, it securely mounts to the switching unit with an air hose. A pulse of air starts the disposal running while shutting off the second outlet. A second pulse makes the disposal stop, and reactivates the second outlet. System is perfectly designed for instant hot and disposal packages. Available in a variety of finishes, this item is sure to complement your existing decorative fixtures while increasing disposal safety."
