  • Add remote control to virtually any switch or outlet
  • The smallest inline module ever! Fits into almost all boxes
  • Turn your antique, custom color or non-standard wall switches into home automation switches
  • Wire in behind your existing switches, outlets and above your light fixtures
  • Sense wires allow for control via a connected, hard-wired switch
  • Compatible with latching switches as well as single momentary and dual momentary switches

Essential Info

Adding remote control to wired lights usually means replacing switches, not any more. With INSTEON's new dual-band Micro On/Off Module, you can keep your antique, toggle or decorative wall switches while adding the same remote control functionality of SwitchLinc.

This compact module installs behind your existing switch, giving it full INSTEON automation while retaining local control at the switch by way of sense wires. Connect the sense wires to any style wall switch to match any type of designer theme (antique, push-button, metal, etc.) Micro On/Off is so tiny that it can be installed as an in-line module within a fixture box, providing remote control without having to run wires to a wall switch.

INSTEON also offers a Micro Dimmer Module and a Micro Open/Close Module.


What's Included

  • INSTEON Micro On/Off Module
  • Quick-Start Guide
  • More Info

    INSTEON Micro On/Off is compatible with latching, single momentary and dual momentary switches. By default, it comes programmed for latching switches such as paddles and toggles; it is easily configured for single and dual momentary switches with a simple reprogramming procedure during installation.

    Due to its hidden nature, we highly recommend using a home management controller (such as HouseLinc) or the free INSTEON app with INSTEON Hub to manage Micro Open/Close.

    GUILHERME MATEU -- trememb, XX   8/11/2014
    Easy to install
    JERRY -- yonkers, NY   8/6/2014
    Work as expected. Fit behind two outlets nicely for my backyard motion lighting project. I have 4 RAB Stealth motion lights connected in series. The On/Off module is always on allowing the motions to work as intended. Where the On/Off comes into play is when I want to keep the lights on manually by turning on my patio Switchlinc switch. That runs a program to turn the On/Off module off/on/off/on within two seconds to trigger manual mode on the lights. When I tuen the patio Switchlinc off, the On/Off module goes off for 10 seconds then back to putting the motions back into "auto". Couldn't be happier.
    RICHARD -- salem, NH   7/23/2014
    Works great.
    JOHN -- katy, TX   7/15/2014
    Worked perfectly and actually did fit inside the 2-gang box well,
    LEO -- scottsdale, AZ   7/14/2014
    I have been using this about a month and it has worked great. I now use it in a scene setting using the INSTEON HUB and it was easy to setup..
    Patrick -- winnipeg, Manitoba   7/14/2014
    I installed the 2442-222 Micro On/Off relay into my over head range to control the fan. This will be used as part of my HVAC solution to control and maintain the homes ambient temperature and humidity. The device will be controlled using the ISY-994iZ HA controller from UDI. The system works perfectly and the 2442-222 is a stellar product. The device is small and has a great form factor but should have mounting holes so it can be screwed in or wired tied for various installs. For my install I used double sided 3M tape to affix the unit. I will be buying many more of these devices as they are a great solution to deploy Insteon control in the home.
    BLANCA MAYELA -- hidalgo, TX   7/10/2014
    Excelent Product. Works as described. I have been using this device for a month to control front lights at sunset and so far never failed. Very reliable.
    DAVID -- federal way, WA   7/10/2014
    I'm using these modules in table lamps, floor lamps and desk lamps. I just wire them into the base of the lamp. Much nicer looking than those external modules that plug into the wall. I had to get the basic on/off since all most everything in my house these days is a CFL bulb and don't dim. As far as wiring goes very simple to install, if you understand basic household electrical concepts. Lamp wiring is much lighter weight and more flexible, than household electrical cabling, so I had no trouble with the screw connections. I even wired one into the Rangehood to control the light in it. Very happy with the product.
    Jerry Spallone -- United States   6/17/2014
    I installed bathroom fans in each of our upstairs bathrooms. I installed junctions boxes in the attic using power that was already in the attic. For one fan I used the old style InLinelinc I had purchased previously for a lamp post future project and this micro on/off for the other fan. Linked each to their respective Switchlincs and they both work perfectly. No more moist bathrooms. The fans and modules can easily be serviced in the attic if need be.
    J STEVEN -- parker, CO   6/15/2014
    I purchased two of the micro on/off modules to replace the OutletLinc relays, controlling under cabinet lighting, since they were not dual band; I was having issues getting the devices to respond after purchasing new appliances. One junction box is plastic and the other is metal; blocking the wireless signal to control the module. I had to modify the module's antenna (small wire taped to the outside) and extend it about 6 inches. The extended antenna was then taped to the underside of the face plate for the outlet. Works perfectly every time! I hope this helps someone else! Be sure, if you have to modify, re-tape the module's antenna back down to prevent damage and insulate any exposed wires!
    TONY -- cherry hill, NJ   6/12/2014
    Awesome little device - I put up a security/flood light and still wanted a wall switch so this was the perfect choice considering I didn't want to run wire from the light all the way to the outlet location. There is a slight delay in hitting the switch and when the light actually comes on but we are only talking seconds maybe 2/3 at the most.
    MARCELO -- sao paulo, XX   5/21/2014
    The sensing wires could be more robust
    Peter Shipley -- United States   5/18/2014
    bought as the offical recommend replacment for the 2475S2 In-LineLinc Relay with sense. After installing I discovered it was not compatible given it fails to support disabling the sense function via fast on & fast off like the 2475S2. Currently smarthome offers no work around or solution other then installing a 2nd device in tandem on each circuit not a real solution or setting up a script to manually send off commands when the unit is activated even less a solution Other problems : the sense wires are too fragile, break easily & are not replaceable. should be a screw terminal like all other connections
    MICHAEL -- winston salem, NC   5/11/2014
    For a non-electrician these were easy to install and a great addition to our home lighting system. Wish I had found Insteon sooner!
    DAVID -- maple grove, MN   4/20/2014
    Similar to my review of the micro dimmer module (2442-222), overall works well and really nice.
    Falc -- boca raton, FL   3/17/2014
    Used this to control my old X-10 floodlights that were not always working. I disabled the X-10 device inside my floodlights and replaced it with this smart home device. I now can properly control my flood lights with my ipad app, turn on/off with a schedule and it still works with my all my old X -10 controls. I can't ask for more than that. Great device!
    BILL -- camarillo, CA   2/25/2014
    Order received promptly, kept as spare.
    FENTON -- melbourne, FL   1/26/2014
    Easy installation. Fits in existing box, even with large switches and rheostats. Can use existing switches, don't have any problems matching colors.
    PIERRE -- carleton place, ON   1/18/2014
    Probably one of the coolest home automation devices I ever bought. The fact that it turns an everyday switch into an insteon device is fanominal. I installed mine on the light of my range hood over my stove. This is perfect for this type of application. The best part is that it turns the on off button into a toggle button. Very cool.
    STEVE -- san jose, CA   1/12/2014
    Should be $25, then would give it 5 stars. Nice, compact device. Great that it is dual band. Should be cheaper. Also, should have a way to tuck in unused yellow/purple wires.
