It’s a device that uses air pressure to operate the disposal unit, providing a safe and convenient alternative to traditional electrical wall switches. 

Here’s a detailed explanation of how it works and its benefits:

1/ Components

Button: Mounted on the countertop or sink, the button is designed to be easily accessible.

Air Tube: A small, flexible tube connects the button to the control unit.

Control Unit: Installed under the sink, the control unit is connected to the garbage disposal and the electrical power source.

2/ Operation

Pressing the Button: When you press the button, it generates a burst of air.

Air Pressure Transmission: This burst of air travels through the air tube to the control unit.

Activation: The control unit receives the air pressure signal and activates the garbage disposal by completing the electrical circuit.Turning Off: Pressing the button again sends another air signal to the control unit, breaking the circuit and turning off the disposal.

Benefits of Using an Air Switch

Safety: Since the button does not carry electrical current, it significantly reduces the risk of electrical shock, especially in wet environments like the kitchen.

Convenience: The button can be installed in a convenient location on the countertop or sink, making it easier to turn the garbage disposal on and off without having to reach for a wall switch.

In summary, an air switch for a garbage disposal enhances kitchen safety and convenience by using air pressure to operate the disposal, eliminating the need for electrical components at the point of activation.
