Blanco 443155 Air Switch Set

It's a sink-mounted air switch for garbage disposal control. You press the button on the deck, air travels through the tube to a controller that switches the disposal on and off, so there is no line-voltage wall switch involved at the sink. Blanco lists it as an air switch accessory for sink applications, part number 443155.

Matte black, and that's the only finish offered under part number 443155. If you're matching a faucet or soap dispenser in a different finish, you'll need a different Blanco air switch part number.

The button itself carries no electricity. An air switch moves a puff of air down a small tube to a control module that does the actual line-voltage switching, so the deck-mounted part of the job is plumbing work. The module still has to be powered and wired to the disposal, and that portion follows normal electrical practice for your jurisdiction.

It suits those units well because the control at the sink is pneumatic, not electrical, which keeps a wet-hands switch away from line voltage. The trade-off for a property manager is that the button, tube, and control module are a set of parts rather than one wall device, so keeping a spare on the shelf matters if you standardize across units. Blanco supplies this one, 443155, in matte black.
