Feature Remote Control

Remote Control

This is no ordinary wall switch. Insteon Wall Switches can be remotely controlled from almost any device in your home: Sensors monitoring doors, windows, leaks and more, remotes, keypads and other wall switches throughout your home, even your smartphone when used with the Insteon Hub.

Feature On/Off Dim

On/Off or Dimming

Whether you need the raw switching power of our 1,800W-relay-based On/Off Switch or the gentle dimming grace of our traditional Dimmer Switch, there's an Insteon Wall Switch to fit your switching needs.

Feature Scenes


One of the most powerful features of Insteon switches, Scenes let you control multiple devices simultaneously with a single tap. Brighten all of the lights in an entire room with a tap-and-hold or create infinite virtual multi-way switches.

Feature Customizable


No wall switch is more customizable. Change the paddle color to suit your décor needs. Swap out the LED light pipe for personalized colors. You can even custom-etch text onto the switch paddles for ease-of-use in multi-gang switch boxes.

Remote control from your smartphone.

Your smartphone is your best friend. And with the Insteon Hub., your smartphone is your Wall Switch's best friend, too. Use your smartphone or tablet to control and configure your switch for the ultimate in remote control.

Feature Remote Control

Remote Control

Sometimes the couch is just too comfy and that wall switch is just too far away. Grab your smartphone and brighten and dim your switch to your heart's content.

Feature Schedules


Automatically turn your porch lights on at dusk. Wake up to a gentle pseudo-sunrise at 7AM. You can schedule individual wall switches or full groups of switches for particular hours and days of the week.

Feature Linking


Linking couldn't be much easier, simply press and hold the set button located right below the paddle until the device beeps. Insteo switches can be linked to multiple Insteon devices such as sensors, plug-ins, and other wall switches.

Feature Scenes


With the Insteon Hub, scenes really take on a new level. Program one switch to turn off all of the downstairs lights. Configure another to turn on Movie Mode. And because you can schedule scenes, you can give your home that "lived in" look even when you're away.

Remote control from another Insteon device.

Insteon devices throughout your home knit together a web of control, enabling some of the most customizable and configurable control options that put even the most expensive home automation technologies to shame.

3 Way Config

The Infinite 3-Way

With traditional wall switches, control from multiple locations, like in a long hallway, requires special dedicated wiring. Great if you're building anew, but almost impossible to retrofit. With Insteon, every wall switch can control every other wall switch, no extra wires needed. Just a few taps of the set button and you've made a 3-way switch. Want to add another? Make it a 4-way - or 5-way. There's no limit to Insteon's multiway switching.

Anywhere Switch

Sometimes you have to wonder what the electrician was thinking when he wired your home. The light switches are on the wrong end of the room, behind doors - just in the wrong places. With an Insteon Wall Switch and a Mini Remote, you can put a wall switch anywhere you want. Mount one on the wall by your nightstand. Give one to your kids and let them investigate the monsters under their bed.


Consolidate Control

With at least one light switch in every bedroom, multiple in every bathroom, a myriad in the living room, den, kitchen and dining rooms, you might have 40 or more switches to manage in your home. With an Insteon Keypad, you can quickly control all of them for instant an instant "good night".

Remote control with Insteon sensors

Your Insteon Wall Switch can do so much more when given access to the family of Insteon sensors. With a few taps of the set button or a moment's time with your smartphone, you can configure sensors throughout your home to automatically turn on (or off) the lights based on a variety of different actions.

Remote Control Doors


There are some rooms in your home that, no matter what time of day, you always end up turning on the lights: Pantries, closets, hallways, etc. With an Insteon Wall Switch and an Open/Close Sensor (or Hidden Door Sensor), you will never need to turn the light on again. And better yet, you'll never need to remember to turn it off.

Motion & Occupancy

Do you play whack-a-mole all day, turning off the lights in rooms that your significant other or children have habitually left on? Turn every Insteon Wall Switch into an occupancy-sensing switch with an Insteon Motion Sensor. And with Insteon, your Motion Sensor can control multiple Wall Switches simultaneously for large rooms or long hallways.

Smoke Bridge


No one wants to think about the potential for a disaster, but if one were to happen, make your escape as safe as possible by automatically turning on lights to an escape path when Smoke Bridge detects smoke, fire or carbon monoxide from a linked First Alert OneLink detector.

Garage Door

It's no only cool, it's handy too. Whenever you open your garage door, turn on the overhead lights for easier entry and exit from your vehicle. And while you're at it, turn the outside sconces and walkway lights on, too for that extra bit of illuminated peace-of-mind when you come home late at night.

Great product Review by Robert J.

The dimmer switch I had very easy to set up and awesome to use! Once the dimmer switch was installed, in a few easy steps I was able to connect it to my Alexa. From there, I set schedules and scenes in the app to turn on while I was trying to wake up in the morning as I'm a very heavy sleeper. The app function is okay, but the dimmer switch was relatively simple to install and set up. Overall, 5 stars!

Alexa control incomplete Review by Don

This dimmer works fine with a few LED recessed lights. I would like to be able to preset the level (to say 50%). The iPhone Alexa app (w/ Insteon hub) often displays "There was a problem" and gives incorrect information. If you set the power to 50%, turn the light off and then on, the Alexa app display says 50% but the lights are at full power. Likewise the Alexa app may or may not display the correct on/off status.

trouble Review by Jacqueline

I have trouble with the app crashing all the time. They are too expensive to not work right.

Nice switch with good feel Review by William

These paddle switches have a good look and feel to them. The on/off and dim function well and without any hassles. Connected easily to my Hub and responds quickly to commands via app or via Echo.

I had purchased similar switches from Smart home about 10 + years ago (all X-10) and although almost all of them were still working replacing these switches every ~10 years or so due to new tech and the occasional malfunction seems reasonable.

Next up for install are the 6 button keypads and fan lincs for the 3 fans in my home.

Great product Review by Eric

Great product, responds to all most all of the commands from scenes as well as programs from the ISY controller. Absolutely a staple for any home automation system.

Great Product Review by Wayne

I have many of these switches and never had a problem with them. They also work great with Amazon's Echo Dot. It is also great to know that I have control over so many SmartHome devices and lights inside and outside my home while we are away.

A good dimmer-expensive and costly shipping Review by Frank

I have a bunch of these dimmers around the house. They work very well and do a nice job dimming modern LED bulbs.

I'd have more, but they're expensive and the shipping cost is ridiculous. At this point I'll keep an eye out for a sale.

These switches saved a ton of time Review by JPR

I had a situation where I wanted to separate lights controlled by two separate switched to operate in concert. Was looking at ripping apart walls and ceiling to change wiring when Insteon came to the rescue. Simply replaced both switches with these switches, linked them together, and voila a "magic" 3-way switch system with both lights controlled in unison by either switch!
