Micro On/Off Switch Module

I used this module in conjunction with a #74551, I/O Module-Garage Door Control & Status Kit to control an LED pilot light, alerting when the garage door is open. The module easily installed in a single-gang box allowing plenty of room for the LED indicator with a rear mounting depth of about 1-½”.

(View the attached photo to see how the LED indicator looks installed, sitting adjacent to a #2487S On/Off Keypad, 6-Button - configured to control a #2475F Ceiling Fan and Light Control Module).

My latest addition to my Insteon home was this nifty micro on/off switch module. My use case was a tripping GFI in the garage by which a freezer was powered. We know that freezers leak current making GFIs prone to trip. A trip happened once but luckily I caught it when the wife complained about the washer not starting. I asked the team at Insteon what I could do and this switch was suggested. It works perfectly. So why the switch is excellent (and tiny), the kudos go to the Insteon team for suggesting it. When you have a problem, send them an email. You won’t be disappointed.

I won't dwell on the need too much, RIP 2477-SA. I built my own 220v contactors for my pool and spa pumps. Any of the on/off switches would have worked but the micro on/off turned out to be the best choice. The micro was easy to attach to the circuit board (zip ties) and has easy access screw connections. I didn't need to use the sense wires but adds flexibility if in the future I want to add an additional local control.
The micro, while on schedules, also allows me to use Alexa and Google to control the pumps. The 2477's couldn't do that.

I have several of the micro switches and they function fine for years as well as switches and some plugins. I just used a micro switch to energize the coil of a 120v contactor that switches both poles of the 240v water heater. ( my device is in parallel or jumps a mechanical clock timer) Total success if the water heater is required outside of the programmed schedule I just switch the heating elements on an hour in advance and approximately 50 gallons of hot water is available

I'm installing a lighted address sign on alive circuit and didn't need it on during daylight so I wired in the micro switch and connected it for sunset sunrise. When the siding is done I'll come back and attach a pic.

I needed a way to control my newly installed flag light without needing to install a physical rocker switch. The power source is near the ceiling in the garage. I COULD have installed a box and switch but it was complicated by the construction of the house. The on/off module allowed me to have the switch at the main junction box. I programmed my Alexa to control the module and also installed a micro remote in the event I need to control it manually.

Sensing wires are too small of a gauge. I wish they were about 16 awg. I realize they do not carry any real current, but it would make them easier to work with and attach to a standard light switch.

Micro switch works really well. Communication speed with outlet is really good. Programming without the hub was not too hard. My only complaint is the size of the relay. I could not fit the relay in a 3 gang box behind the switch that the relay was coupled with. I had 4 pieces of 14/2 in a 3 gang box, and the relay just would not fit. The relay was bigger than I was expecting. But other than that, product is great!

I installed this switch to control my towel warmer. It’s attached to a SPST 2-way switch. Nothing fancy. Works just like it should. Very pleased.

I have a dozen or so of these devices on my HA system, Some for lighting, one to automate a sun shade, another to automate a gas log set. Also use 8 of these to fully automate my shop dust vac system. Of the bunch 3 have failed over time others have lasted 10 plus years. The small size makes it possible to use these in small spaces which is a big plus in my applications. Dropped won one star due to the failures.

The Micro on/off switch fits nicely in my swimming pool light's weatherproof electrical box. I had a full-sized In-LineLinc On/Off in there before but a nearby lightning strike took it out.

I replaced another In-LineLinc in my workshop dust collector that met the same fate.

Smaller the older versions so it fits better into electrical boxes and so far it works just as well. Also easier to install and sync with other switches.

Its been about 5 years since I installed 3 Micro On/Off switches in my attic.
Two of them control my attic fans, and one controls outdoor lighting.
My attic can get up to 120 degrees with the fans running, and before there were fans, about 150 degrees.
These Micro On/Off switches have operated flawlessly, even in the extreme heat,cold. and summer humidity in my attic.
Keep up the good work Insteon.

Many or most LED fixtures nowadays support a 0-10V dimmer standard. (It uses low-voltage control wires between a controller and the fixture for dimming.)
With Insteon controllers, I have been having to forego using that functionality in my new fixtures. Insteon, please catch up! (Insteon’s only 0-10V dimmer support is for a “ballast” controller for dimming fluorescent fixtures.)

Anyway, the compact size of the Micro On/Off Module is definitely appreciated.

Easy install and fits my needs.

I was installing a new LED mirror in our bathroom. Of course, there was only one hot wire going to the bathroom light, and I didn't want the mirror turning on every time we turned on the bathroom light. I replaced the old switch with an Insteon On/Off switch, then added the Micro On/Off Switch Module inside the bathroom light fixture. The mirror now has constant power and can be turned on/off with its own switches, and the light fixture is turned on or off with the Micro On/Off Switch Module. It easily fit inside the body of the light fixture, and the screw terminals take up much less room than the old-style module with wired connections. The screw terminals easily accept 12-gauge wire. You just need a screwdriver small enough to fit the holes in the module's body.

Insteon works good but is expensive. No hurry shipping via USPS.

Micro On/Off Switch Module

I bought the Micro On/Off Switch module to replace a failed older module. It was not a "drop-in" replacement, as the wiring is different. But after wiring it up, it worked perfectly immediately. Since I now know more or less what I'm doing, I'm thinking of wiring up in the "signal" lines to give local control that I didn't have before. Great module!

I acquired the micro on/off switch as a replacement for my Insteon Inlinelinc switches since Inlinelincs are no longer being produced by Insteon. Given that context, here are my observations:

• The form factors for the Inlinelinc and micro on/off switch are significantly different. The micro on/off switch does not fit in my Insteon panel and special accommodation has had to be made.
• I use Universal Devices (UD) software to configure my Insteon devices. The micro on/off has configuration limitations that have made it harder to configure and control using UD. Since UD software is fairly complete, I assume that any limitations are with the device, not UD software.
• It’s my impression that the micro on/off switch had problems manually syncing with its paired controllers. Multiple attempts were sometimes required to complete functional control connections.

All in all, I’m sorry that the Inlinelinc units are no longer available. The micro on/off switch is an adequate substitute, but just barely.

I’m grateful that these are available again. The micro on off is easy to install and connect to the system. I used it along with two relays to control (240v) pool pump (mimicking a 2477SA that failed and is no longer available).

The Micro On/Off Switch and it's cousin the Micro Dimmer switch is the most versatile product from Insteon. Yes, it's a great way to easily add a switch or a new location of a switch for a light. No new wiring to run. Place the Micro switch in the box where the light is electrically connected and use a remote to turn/off/dimmer your light. Where I believe the Micro switch excels and where I use them all the time is where there is no switch. For example, controlling the transformer for your outside landscape. I use them for this an other devices like pumps on an outside fountain or water fall. Once in place you can set schedules or use Google or Alex for voice control. How about outdoor flood lights. Imagine being awakened by a noise in your yard or house just after you jumped into bed. No problem, just tell Google or Alexa to turn on the floodlight(s). I have used these switches and dimmers for years. There is no other product like this on the market.

Love the reliability and ease of set up with the Onsteon technology.

Excellent for adding control for a device when junction box is much too high for a switch. Allows the 2443 to be placed behind a regular outlet or switch.

I’ve been using these in landscape applications where I couldn’t use traditional switches. I use them to control my outdoor fountains, landscape lighting, etc. They are all in outside boxes sheltered from direct sunlight. These been working reliably for over 10 years in Phx where summer temperatures often go above 115degF. I did take care to place their boxes in shady areas and one is in an external box on the house. No issues, no failures. My outdoor GFCI plugs fail far more often than these.

Steve Lee gave me the Klever idea to use the Micro on/off module to monitor when my well pump is running or not.

It’s so much simpler than my way I was thinking of. You just use the Yellew sense wire and connect it to the well pump pressure switch.

Time will tell how long this will work since it is outside in the elements but should not get wet ever.

Thanks Steve Lee and Insteon.

I will try to get more familiar with micro modules since it worked out so well for the Well pump project.
