Essential Info

Similar to the best selling SwitchLinc Dimmer, this newest member of the SwitchLinc family requires only two electrical wire connections. Meaning that if you don't have a neutral wire available in your switch box, you can finally incorporate those locations into your INSTEON network.

How is the SwitchLinc 2-Wire Dimmer different than the SwitchLinc family of dimmers?

  • More Info

    Slim Design
    Similar dimmers are up to 50 percent deeper than the SwitchLinc Dimmer. Thanks to its slim design, it makes installation easy even in small junction boxes.

    Beautiful, High-Quality Construction
    Unlike other switches, the SwitchLinc Dimmer offers the natural feel of high-end dimmers. You'll love the crisp, tactile response with each touch instead of the mushy feeling of other brands. The SwitchLinc Dimmer is designed and manufactured to high-end specifications and goes through over 10 quality control tests before arriving at your doorstep. This modern Decora-style switch will blend with any room's design. Additional color options are available with replacement paddles (sold separately).

    Scene Lighting
    Scenes allow you to control multiple lights, rooms or even the whole home with a single command. Because the SwitchLinc Dimmer can be a member of more than 400 scenes (i.e. "Movie Time," "Party," "Romance," etc.), you'll be able to launch various lighting scenarios with a single button press. These are elegant features usually found only in systems costing tens of thousands of dollars and requiring extensive rewiring of your home. All member lights can ramp to your independently desired brightness levels at your chosen ramp rate(s). So one set of lights can dim slowly, while another set turns off instantly, all controlled with one command from one button. If you want to control multiple scenes from one controller, we recommend the INSTEON KeypadLinc Dimmer.

    Non-Volatile Memory
    All SwitchLinc Dimmer settings are stored in non-volatile memory and are not lost during power failures. Additionally, in the event of a power loss, the SwitchLinc Dimmer will return to its last brightness level when power is restored.

    Note: As with all wall dimmers, the SwitchLinc may feel warm during operation. Rigorously tested and approved to UL-standards, the amount of heat generated falls well within approved limits and poses no threat to your home or the lifespan of the device.

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

    Wrong switch was recommended to me. Had to return it.
    DAN -- redmond, WA   2/28/2014
    Installation was very easy
    BBPDEG -- fresno, CA   2/3/2014
    I installed this two wire switch in a room with a fan and light. I wired it into the light portion which has LED lights in it. It works perfectly dimming, on, off, etc. Sorry Ronald couldn't make it work.
    RONALD -- chicago, IL   1/4/2014
    The description didn't clearly say that this switch wasn't compatible with LED lights,
    HEATH -- st. peters, MO   1/3/2014
    Works great.
    GREGORY -- gold canyon, AZ   1/3/2014
    This one of dozens of Insteon products that I have bought over the years. This was needed because of a two wire configuration at a BBQ island. Worked great.
    MICHAEL -- glendale, CA   11/16/2013
    Solved my incorrectly wired switch problem. My only want is I wish they made this in a traditional switch version instead of modern, as I have a 90 year old house.
    SCOTT -- lakewood, CO   8/23/2013
    Works as directed
    RAUL -- san francisco, CA   6/19/2013
    Received the product on time and works great.
    MICHAEL -- plano, TX   6/2/2013
    Great solution when there are only 2 wires. Looks the same from the outside as the 3 wire switches.
    JOHN -- alexandria, VA   5/24/2013
    Works most of the time.
    MICHAEL -- audubon, PA   5/7/2013
    Great Solution for a 2-Wire switch. I am happy to see this product in the line up.
    HEROILDO -- milton, GA   3/25/2013
    It works as expected.
    JONATHAN -- longmont, CO   1/3/2013
    Works great
    Ben -- California   1/1/2013
    Great idea to support withot neutral wire, but this is 2013... why doesn't this support CFL/LED properly? Even non-technical switches support this without use of neutral. Please have better bulb support!
    Smarthome Responds: Ben: in order for the 2-wire SwitchLinc to work, it must pass a small amount of power through the filiment of the incandescent bulb. Because CFL and LED bulbs operate at such low wattages, this small amount of power would actually light the LED bulb and most likely flash the light on a CFL. If you have a neutral wire in your switch box we recommend going with a #2477D or you could always simply replace the bulb itself with the INSTEON LED Bulb #2672-222
    KENT -- ketchikan, AK   12/30/2012
    Solved older house wiring issues. I would like to see a SwithchLinc 2-Wire Switch!
    DANIEL FLORES -- aliso viejo, CA   12/1/2012
    Works perfectly every time, and but the color of the paddles all on I've received has been a harsh, cold white, and do not match any of my existing white switches or trim. Thankfully, they sent me a paddle replacement kit of the same color, but it actually matches.
    DANIEL FLORES C -- aliso viejo, CA   12/1/2012
    Works perfectly every time, and but the color of the paddles all on I've received has been a harsh, cold white, and do not match any of my existing white switches or trim.
    D Tice -- Long Beach   10/27/2012
    Finally! I have an old house and was disappointed when I found that Insteon switches required Neutral in the box. I was using X10 and switched to Insteon. The 2 wire switch works like a charm. Now if they could just figure out a way to make a Non-Dim for fluorescent and LED. The switch also worked without any issues with the ISY-99i
    LUIS CASTRO -- naucalpan, XX   10/22/2012
    Great product! I have several boxes with no netural and the product worked great there. Keep in mind you need to have at least one dual band devices for this dimmer to receive signals. Only problem was the documentation was incorrect regarding setting the LED brightness (I had to refer to the 2477D manual).
