InSinkErator Sink Top Air Switch Garbage Disposal Button Dua

The Verdict

Let’s cut to it: if you’re tired of reaching under the sink for that little wall switch every time you grind food scraps, the InSinkErator Sink Top Air Switch is the upgrade you didn’t know you needed. At 4.7 stars across 235 ratings, it’s clearly doing something right. But is it right for your kitchen? Here’s the real story.

What’s Actually in the Box

You get the chrome air button assembly, a 3-foot pneumatic tube, and — the standout feature — a dual outlet power module. That second outlet is the reason this version costs more than the single-switch kit. You can wire your disposal into one outlet and a second appliance (instant hot water dispenser, under-sink light, even a reverse osmosis system) into the other, all triggered from the same button. Most buyers don’t realize this flexibility exists until they read the fine print.

The button itself is solid metal, not plated plastic. It’s designed to drop into a standard 7/8-inch sink hole — the same size used by most soap dispensers and sprayers. If you’ve got an unused hole in your sink deck, installation takes about 20 minutes.

Performance and Real-World Use

The pneumatic mechanism is the genius part. There’s zero electrical current near your water source. Press the button, it sends air pressure through the tubing to a control box that switches the outlet on. That’s it. No GFCI concerns, no fishing wires through the cabinet, no electrician.

One thing buyers consistently mention: the button has a satisfying tactile click. It’s not mushy like some cheap air switches. You know it engaged. One verified reviewer put it this way: “I installed this in 15 minutes and it works flawlessly. The dual outlet is perfect for my disposal and insta-hot tap.”

Another common thread in the reviews is the reliability over time. Several long-term owners report no issues after 12+ months of daily use — no stuck buttons, no leaking air lines, no intermittent failures. That’s the kind of durability you want from a component that lives under a sink where humidity and temperature swings are common.

Where It Falls Short

No product is perfect, and this one has two quirks worth knowing before you buy.

First, the tubing is sensitive to sharp bends. If you route it around a garbage disposal unit or a P-trap with a tight 90-degree angle, it can kink and cause the switch to feel sluggish. You’ll want to give it a gentle, sweeping curve. Buyers who had problems almost always traced them to installation, not the product itself.

Second, the button protrudes slightly above the sink deck. It’s not flush like a pop-up drain. If you scrub the sink aggressively with a stiff brush, the sponge can catch on the edge. Minor annoyance, but worth noting if you’re obsessive about a perfectly flat sink surface. Some owners solve this by mounting it in a less-trafficked corner of the deck.

Who Should Buy This

• The DIY homeowner who’s comfortable with basic hand tools but draws the line at electrical work. This is genuinely plug-and-play.
• Anyone with a dual-appliance setup under the sink — you’ll appreciate the second outlet instead of buying two separate switches.
• Kitchens with kids — no wall switch at child height, and the button requires a deliberate press, not a brush-by bump.

Frequently Asked Questions

Q: Does this work with any garbage disposal brand? A: Yes. The air switch controls the power outlet, not the disposal directly. If your disposal plugs into a standard 120V outlet, this will work. InSinkErator, Waste King, Moen — all compatible.

Q: Can I install this myself, or do I need a plumber? A: If you can use a screwdriver and have an accessible outlet under the sink, you can do this yourself. No plumbing knowledge required. The hardest part is feeding the tubing through the sink hole, which takes two minutes.

Q: What happens if the power goes out? A: Nothing. The button stays in whatever position it was last in. When power returns, the disposal resumes its previous state — it won’t suddenly turn on. That’s a safety feature, not a bug.

The Verdict

Buy it if you want to eliminate the awkward wall switch, especially if you have a second under-sink appliance to power. The dual outlet makes this the smartest value in the air switch category.

Skip it if you have only a single disposal and a tight budget — the single-outlet version will save you a few bucks. Also skip if your sink has no spare hole and you’re not willing to drill one.

Rating: 4.6/5 — It does exactly what it claims, installs cleanly, and saves you an electrician visit. The minor tubing sensitivity costs it a half-star, but for the convenience and safety, this is a solid buy for anyone tired of fumbling under the counter.
