Use this Westbrass Air Switch with ANY brand of garbage disposal unit to protect the user from electrical shock. 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 a combination of instant hot water dispensers and disposal packages. Available in a variety of stylish finishes, empowering you to perfectly match your air switch kit with your existing faucet, kitchen hardware, and unique style, ensuring a cohesive and polished look that elevates your kitchen's aesthetic.
