Sink Disposal Air Switch Button

The Kingston Brass KA21VN air switch button mounts on a sink or countertop and connects to a hose that sends a pulse of air to activate a garbage disposal. It is intended for homeowners or installers finishing work around a kitchen sink who want a countertop-mounted control instead of a wall switch.

Finish and Colour

The button is supplied in a black stainless finish and is described by the manufacturer as transparent in colour. This specific finish determines whether the button matches the surrounding faucet and decor, so buyers must verify the look before purchase.

Proposition 65 Notice

The product carries a California Proposition 65 warning stating it contains a chemical known to the state to cause cancer and birth defects or other reproductive harm. No thermal, noise or power-draw data is provided for this pneumatic accessory.

Questions about this item

How does the air-switch button actually operate the disposal once it is installed?

Pressing the button sends a pulse of air through a hose to a control unit under the sink, which then starts or stops the disposer without any electrical contact at the countertop.

What connection does the button use to link with the disposer control?

A flexible air hose runs from the back of the button to the pneumatic actuator on the disposer power module.

What size hole is needed to mount the button in the sink or countertop?

The button is designed for a standard 1-3/8 inch cut-out, the same size used for most sink accessories.
