A garbage disposal air switch activates your disposal by pressing a button which sends a pulse of air through PVC tubing to a control box underneath the sink which contains an air pressure switch.  The disposal air switch is compatible with most garbage disposals and installation is easy.

 

The disposer gets activated by the air switch which in turn passes a thump of air through another connecting tube that is connected to the control box which is placed under the sink where there is an air pressure switch.  This air switch is easy to install and works with all disposer models.
