KRAUS Garbage Disposal Air Switch Kit

The Verdict

If you’ve ever flinched reaching under the sink for a wet wall switch, the KRAUS Air Switch Kit is the cure. It replaces that electrical toggle with a sleek countertop button that uses air pressure to trigger your disposal — no wiring, no electrician, no shock risk. At 4.7 stars across 235 ratings, it’s clearly doing something right. Here’s the full story.

What’s in the box
The kit includes the brushed nickel button assembly, a 1.2-meter PVC air tube, the control box that plugs into your disposal (standard 1/2-inch or 3/4-inch HP units), and two knockout adapters — 1.5-inch and 1.25-inch — so it fits most sink holes without drilling. You also get foam gaskets and a mounting nut. The control box is UL-listed, which matters when you’re dealing with water and electricity in the same cabinet.

Performance and build quality
Installation is genuinely straightforward. You mount the button in an existing sink hole (or drill a 1.25-inch hole — the template is included), route the tube to the control box, plug the box into the disposal, and plug the disposal into the wall. The air tube is stiff enough to route cleanly but flexible enough to bend around drain lines. No electrical work required, which is the main selling point.

In daily use, the button has a crisp, tactile click. The air tube transmits pressure instantly — no lag between pressing and the disposal kicking on. The brushed nickel finish is durable; it won’t show water spots like chrome does. One reviewer noted, “I’ve had mine for eight months and it still looks brand new, even with daily use.” Another said, “The button feels solid, not cheap plastic like other kits I’ve tried.”

What buyers consistently praise
The safety angle is the top reason people buy this. Multiple reviewers mentioned installing it after a child flipped the wall switch while their hand was inside the drain. One wrote, “I sleep better knowing my kids can’t accidentally turn on the disposal.” The ease of installation is also a recurring theme — several buyers with minimal DIY experience said it took under 30 minutes. The included adapters get specific thanks, as they eliminate the need to buy extra parts for less common sink configurations.

Where it falls short
The button protrudes about a quarter-inch above the countertop surface. That’s fine for most, but if you routinely slide cutting boards across the sink area, it can catch. Also, this is a momentary-switch design — you must hold the button down to keep the disposal running. That’s safer for kids, but if you’re used to flipping a switch and walking away, it takes adjustment. Some users also reported the air tube can kink if you cram it behind the disposal; route it carefully with gentle curves, not sharp bends.

Who should buy this

• Families with kids — the safety benefit alone justifies the price.
• Renters or condo owners — no electrical modifications means you can reverse this during move-out.
• Anyone with arthritis or grip issues — pressing a button is easier than twisting a wall switch.

Skip it if you have a 3/4-horsepower commercial disposal with a hardwired connection — those need a different control setup. Also, if you prefer a toggle-style switch you can leave on, this isn’t it.

FAQ

Q: Does it work with all garbage disposals?
A: It’s compatible with most 1/2-horsepower and 3/4-horsepower units that use a standard plug-in cord. Hardwired disposals need an electrician to convert to plug-in first. Check your model’s manual to confirm wattage — the control box handles up to 15 amps.

Q: Can I install this without drilling a new hole?
A: Yes — if your sink has an unused soap dispenser or side sprayer hole, use the included 1.25-inch or 1.5-inch adapter. If not, you’ll need to drill a hole, which requires a diamond-tipped hole saw.

Q: What happens if the air tube leaks?
A: The button won’t trigger the disposal if the tube is cracked or disconnected. Inspect the tube annually — it’s cheap to replace, and the control box is unaffected.

The Verdict
Buy it if you want a safer, easier way to control your disposal without hiring an electrician. It’s well-built, installs in minutes, and the included adapters save you a trip to the hardware store.
Skip it if you need a hands-free toggle or have a hardwired commercial unit — this isn’t the solution for either.

Rating: 4.6/5 — a solid upgrade that earns its keep, with only minor ergonomic tradeoffs.
