About the Insinkerator STS-SO

The InSinkErator STS-SO is a single outlet air switch for your disposer. This stylish switch features an air-activated push button which is made to bring maximum convenience to its users. It is a better alternative than to create an electric wall switch and a great addition to your island and regular sink! The power module and the 6-foot-long air tube completes the InSinkErator STS-SO kit with a variety of button finishes that will surely complement any kitchen style and decor. As part of its easy-to-install feature, an installation manual with detailed step-by-step instructions are provided for do-it-yourselfers. This easy-to-mount switch is suitable to fit with all disposers, but the 110V power is required. Also, for extra assurance and peace of mind, the InSinkErator STS-SO is backed by a replacement warranty of 1 year over the counter. On a side note, this switch requires a hole diameter of 1-1/4" and counter thickness of 2". This unit is intended for residential use and not for commercial/industrial applications.

Great idea, not so great quality Rated 2 by Sammy68
I installed the kit two years ago and it was pretty straight forward. The most difficult part was screwing the nut onto the bottom of the button assembly under the sink.

Simple concept; Good execution Rated 4 by DIYer
This product works as advertised. The install is simple. As a previous reviewer mentioned the switch does not sit flush with the surface of the counter and getting it to look perfect is impossible. It sits just a bit above the counter surface. That said, it still looks good and is much better than a big huge wall switch. Operation of the switch is simple - just push down on it. It has worked every time. I did shorten the hose which is said to make operation just a bit easier. I don't know if that is true but it worked for me.

works well Rated 4 by Jiceman
  Yes, I recommend this product.
I installed this after my sink and countertop was installed and I have ti say it was very easy to install and it works well. I have not used it too much but as long as it last for a few years I will be happy with the product.

Switch sticks and plug broke after minimal use Rated 3 by RAGO
I bought this product for an island sink. I liked the idea of not having to reach under the counter or the side of the island to operate the disposal. The installation was easy enough.
