  • Control hardwired lights and appliances without running wires for a wall switch

Essential Info

Control hardwired lights and appliances without a wall switch. Simply wire the In-LineLinc to your lighting or appliance fixture and link it to an INSTEON controller for fast, reliable remote control. No need to pull additional wires for a wall switch!

This latest member of the In-LineLinc family works great in residential (120VAC) as well as commercial (277VAC) applications and offers a higher load switching capacity so you can control larger banks of lighting. In addition this In-LineLinc Relay is dual-band, meaning it communicates simultaneously over both radio frequency (RF) and the powerline, increasing reliability while enhancing your INSTEON network.

Software configurable
Using INSTEON software such as HouseLinc, you can control, program and manage settings for In-LineLinc Relay and any other INSTEON devices in your network. You can even schedule timed events, receive email alerts when devices are activated and more. Learn more about HouseLinc.

Add a Wireless Wall Switch Anywhere
A RemoteLinc 2 Switch can be wirelessly linked to the In-LineLinc Relay and mounted on any wall you where you want control (mounting kit sold separately). The RemoteLinc 2 Switch looks like a standard decorator wall switch but is powered by a USB-rechargeable battery and can go for over a year without recharging under daily use. You can add as many as you want, providing a wireless switch at different points in the room or house.

INSTEON also offers a Micro On/Off Module that wires in behind your existing switches or fixtures. This allows you to keep your existing antique, toggle or decorative wall switches while adding the customizable INSTEON remote control functionality.


What's Included

  • In-LineLinc Relay - INSTEON Remote Control In-Line On/Off Switch (Dual-Band)
  • 4 Wire Nuts
  • Quick Start Guide
  • More Info

    The In-LineLinc Relay is fully INSTEON compatible and X10 ready. Homeowners with existing X10 networks can easily migrate to an INSTEON network without having to discard all their existing X10 devices. X10 ready means that the In-LineLinc Relay can respond to X10 commands from an X10 controller and it can send X10 commands to X10 devices. Please note that INSTEON devices repeat INSTEON signals but not X10.

    Non-Volatile Memory
    All In-LineLinc Relay settings are stored in non-volatile memory and are not lost during power failures. Additionally, in the event of a power loss, the In-LineLinc Relay will return to its last on/off state when power is restored.

    Certifications and Warranty
    All In-LineLinc products are safety approved. The factory for SmartLabs Design Products is ISO9001 certified. Because of this passion for quality, Smarthome stands behind the entire In-LineLinc line of products with a full 2-year warranty.

    JOHN -- montgomery, TX   7/20/2014
    Item easy to install and set-up. The relay allows installation of wall sconces without exposed electrical wires and eliminated need to run wiring for a switch. Great product.
    RICHARD -- austin, TX   2/17/2014
    These are great for remote locations where I can't install a switch box. For example I am using this one in a light fixture in my attic. I then control the light from a keypad link on the ground floor. Don't have to worry about leaving light on in the attic as I can turn it off from anywhere.
    JAMES -- gilbert, AZ   2/6/2014
    Works great, wish it was small enough to fit in the light fixture I used it on, but it did what I wanted it to do.
    CHRISTOPHER -- murrieta, CA   1/16/2014
    I have an older in-linelinc, non dual-band but with sense wiring. I have no communication problems with any of my insteon stuff other than some noise coming through LED lights on the same circuit. I've found most communication issues were a result of a bad program or scene.
    ARTHUR -- woodland hills, CA   12/8/2013
    I'm having some of the same issues that I had with the x-10 stuff, inconsistancy
    ERIC -- edmond, OK   12/5/2013
    Solved my problem works great
    JAMES -- burke, VA   11/20/2013
    I am using this in a sealed outdoor enclosure to control a heavy duty relay for my pond pumps. No problems with reliability and it works a lot faster than my old X-10 control. The status capability allows me to see which pump is on even when it is too dark to see the pond.Taking one star off since the housing has multiple protrusions which hinder placement in a tight box. Replacing pigtails with screw terminals would eliminate multiple wire nuts which also take up valuable space.
    TIM -- long beach, CA   10/3/2013
    Change LED to red/green such as In-LineLinc Dimmer. Love addition of 20A control and local on/off buttons. Lacking full x/10 control. It will only handle a primary address, not scenes in x/10. This deletion completely baffles me since it is just a software issue that is readily available. Here's the biggie; the brackets for mounting in gang box have now been deleted. This unit is so dangerous. I was told by support to just let it sit in gang position, but it can move with heat/cold or vibration and touch up against adjacent gang mounted items such as outlets or the side of the gang box if metal and short out or start a fire. There needs to be an immediate fix for this issue or recalled. INCLUDE removable brackets please.
    MARY -- menifee, CA   9/20/2013
    Works well..Wish the remote switch fit in the wall bracket and switchplate better.
    JAY B -- las cruces, NM   8/5/2013
    Worked perfectly.
    RICHARD -- katy, TX   7/22/2013
    Easy to use,my guys love it. Just wish they were a little cheaper,
    ROBERT -- canton, GA   7/20/2013
    Product support was superb; product supplied was too large for my junction box, so SH recommended another Insteon product that worked like a champ. Good job SH.
    ERIC -- akron, OH   6/9/2013
    Excelent! Though relatively large in size works great in my detached garage behind the motion sensor. I can now turn on the lights from inside the house.
    Craig Baldry -- montreal, Quebec, Canada   6/8/2013
    Easy to set up with SwitchLinc Switch 2477S to remotely control landscape lighting from switch for porch lights.
    TANER -- san diego, CA   4/25/2013
    Does its job!
    IAN -- verona, PA   3/14/2013
    Works as advertised.
    JOEL -- las vegas, NV   3/10/2013
    Not currently using because it does not fit in the j box. Was planning to use it for outdoor lighting. I'm sure it would have functioned OK.
    JULIUS -- holly, MI   2/28/2013
    works as advertised, directions are horrible
    MARLON -- pleasant grove, UT   1/14/2013
    Very reliable!
    BRUCE -- miami, FL   12/28/2012
    All of the Insteon products are very easy to install and integrate with the other devices.
