Intermatic FD60MWC 60-Minute Spring-Wound In-Wall Countdown Timer Switch for Auto-Off control of Fans and Lights, White

Timer description matched the product exactly. The instructions list three different models of this timer switch. The difference between models only appears to be how the wires connect. The timer came with two screws to mount to the electric box, and two screws to make the wire connections. It also came with the timer plate and nut to fasten the plate, and the knob. Wire connections were easy, although you have to look closely to see the molded in "line" and "load" markings. Basically its black wire feed to the line connection, then the fan (or other device) to the load connection. Make neutral to neutral (white) and ground to ground (bare copper) connections as typical of any wall switch. And like the description says, "Supplied with a molded white time dial plate designed to fit either toggle or decorator style switch plates ". That means it only comes with the timer plate, but not a switch plate. (the time dial plate is the rectangle with the time marks on it. It fits a standard wall plate with large rectangular opening). It works as it supposed to and seems accurate with its timeing. The knob was quite hard to turn the first time, but after a few days of use it has loosened up in both directions. The clicking noise of the timer can't be heard over the sound of the whole house fan that is directly overhead. With the power off, I noticed the timer is quiet enough to use with bedroom ceiling fans (which I am considering doing). All in all, its appears to be a good buy. Much less expensive than the choices at the home centers, and at 6 hour timing it is just what we needed for our attic fan. Update: The Master Flow whole house attic fan came with a rocker switch with Off, Low, and High positions. When the fan was installed, I put in a two gang electric box (double box) because I knew I wanted to add a timer. But now with this timer installed, the rocker switch Off position was no longer needed, plus finding a cover plate with the decorator opening on one side for the time, and a custom size hole for a rocker switch on the other was impossible. So I tossed the rocker and got a regular 3-way wall switch, and wall plate with the regular toggle switch opening on one side, and the decorator opening on the other. Then I wired the power to the timer, then to the 3-way. So now the timer functions as the on/off switch, and the 3-way toggle is just High and Low. Much better functionality, and nice clean wall switch plate. The whole house fan I have is a 30" belt drive model that is rated at 4 amps, so this switch is more than sufficient. BTW, the timer switch specs/ratings are: Resistive: 20 Amp, 125 VAC, 50/60 Hz 10 Amp, 250 VAC, 50/60 Hz 10 Amp, 277 VAC, 50/60 Hz Tungsten: 7 Amp, 125 VAC Motor: 1 HP, 120 VAC, 50/60 Hz 2 HP, 240 VAC, 50/60 Hz Operating Temperature: -40¢ªF to 104¢ªF (-40¢ªC to 40¢ªC) Style: Can be used with decorator and toggle type switch plates Dimensions: 2.79" H x 1.6" W x 1.19" D

I was looking for a 15 minute mechanical timer switch, and after reading through the reviews, decided to try this one to control my bathroom exhaust fan. The package includes all the parts you need to install the switch, and the timer readout dial plate fits right over the regular switch plate that you already have. The switch fit perfecly into my double-gang switch box, and installation was a breeze. It took less than 5 minutes. The instructions are clear and easy to understand, just two wires to unhook from your old switch, and attach to the new one. As far as construction, it seems well made. I was a little apprehensive after reading some of the other reviews, but I feel that this is constructed about as well as any off-the-shelf electrical parts you will buy anywhere. Fit and finish were fine. As mentioned in several other reviews, the knob does require some force to mount on the shaft, but that's probably a good thing. It shouldn't loosen and come off after extensive use. In operation, it does make some sound (kind of like a wind-up kitchen timer), but isn't too noticeable when the fan is running. When it reaches shut-off, it makes a distinctive click. You can adjust the time, either adding to or subtracting from it, after making the intial setting. You can turn it back to "zero" to shut it off, but I don't know if that would be good for it if done regularly. I set it for 15 minutes, then turned it back to 5 minutes, and it didn't seem to be any problem at all. Overall, I'd recommend this item. It has a one-year warranty, and was made in Tunisia. Update after 9 months of use: Still going strong as ever. I can only guess how much money it has saved me in lost-heat costs from the house when people used to forget to turn off the old, regular switch, and it would run for hours. Set it and forget it.

Had one of this exact model in a previous residence and it worked for over 20 years. I have every expectation that this one will continue working for that long and likely both will work until the entire system is replaced for other reasons. This timer is simple to install (about ten minutes of actual install work) and simple to use (just turn the dial). If you need a timer that is really accurate, you may need to look into a digital one, since this relies on a spring and no amount of factory calibration will make it that accurate through its entire range, and make it stay that way for decades. I am using this strictly for DC continuity control. What this does provide is a no-power, no-"smart" switch that works right every time, doesn't need your wifi password, doesn't need a subscription, doesn't lose its marbles if you have a power outage, doesn't send your data and usage habits to an aggregator... on and on. I installed this in a junction box, even though in this application it only provides continuity for 24VDC to control a furnace fan. The spring tension also would tend to twist it out of drywall if it were not adequately secured, so a J-box is a good plan. It may also be required per local code; if you're in doubt, check yours before completing your installation.

I just purchased this switch and installed it on my bathroom fan so that I could leave it running for a while after showering. Previously we have been doing this manually, but I usually leave the house right after showering in the AM and so the bathroom was getting mildew. Before buying this switch I bought an electronic timer to install however it turned out my electrical box did not have a neutral connection (as whoever installed my light/fan unit only ran the hot down to the switch box), so using this mechanically (spring) driven switch was the solution. In general I would say the switch is reasonably well made. I see these same brand switches all over the place so they are extremely popular. It was annoying during the install to get the switch lined up in exactly the right spot so that the decora cover plate fit over it. I ended up installing it once with the switch not tightened into the electrical box (so it could move to the right place when I put on the cover), but then once I put the knob on the switch I realized it felt pretty loose and so I went back and tightened down the screws to hold it to the box (just guessing what the alignment should be). Really, the time dial piece of plastic is pretty annoying to install outside of the switch plate - I think they should just build the time dial into the switch (but I think they are riding the fence trying to make one part that works in "classic" light switch face plates and decora style ones. I do have to agree with another commenter that the press-fit dial handle on the front was very hard to put on (plus you don't really know how deep it is supposed to go and when you should stop applying force - breaking the switch is a real possibility). As stated above, I installed the switch twice trying to get the alignment right and pulling the dial handle off was very difficult (resorted to prying with a screwdriver which could mar the switch or the faceplate). This is where I would consider it to be poor quality. (hence only four stars) I also need to call out the instructions from in the box and also posted on this product info page as being poor quality. Specifically, from what I can infer, they offer at least three versions of this switch: Single pole single throw (this one I bought and wrote the review of - it is your basic light switch), single pole double throw (3 way switch), and double pole double throw (i.e. 240v applications where you need to break both "hots"). From what I can glean from the instructions in my package and the wiring examples on this site, the single pole double throw switch actually can do a lot more than that. It seems to have two current paths through the switch, one of which the current is broken when the switch is "on" and one that is closed when the switch is "on". By wiring this switch in different ways you can use it to turn something off during the timed interval, or use it in 3 way situations. They really badly need to provide a series of diagrams that shows the electrical operation of each type of switch rather than just providing specific wiring examples (which they don't explicitly tell you which type of switch you need to buy to accomplish). This is the right switch for a lot of use cases, but I wish there was a slightly higher quality option, better documentation, and a little easier installation in decora style faceplates. -Eric

We have a very large, very bright light fixture in the kitchen. Very nice, but it sucks a lot of watts, and the kids left it on all the time. Twenty seven years ago I bought a 60-minute timer switch at the local hardware store, which solved the problem. It has seen constant usage over the years, often getting forcefully turned off as some reviewers have said not to do. It finally died last month - the switch still worked, but the timer would no longer turn it off. I bought this 30-minute timer as a replacement. As I started the process to replace it, I realized that the broken timer switch was also from Intermatic, and looked identical. Then I noticed two little Torx screws that appeared to hold the clock-spring mechanism. Sure enough, the broken clock-spring mechanism popped right out, so I just replaced it with the clock-spring mechanism from the new part. It worked perfectly. I didn't have to touch the wiring or even turn off the breaker - there was no hazardous voltage exposed. Amazingly easy. I am tempted to buy another to have on hand in case the clock-spring mechanism dies again and Intermatic changes the design, but heck, the first one lasted 27 years, I think I'll just chance it. If only everything in life worked this well.

I have an older mobile home and the one that came with the home failed. I bought this and it works great. Easy to install

Works great

I bought this 2h timer to replace an original 30 min one controlling my Jacuzzi . it is really dumb to install the 30 min timer for that purpose and I should have paid more attention to details when my house has being built. Anyway, the installation was pretty easy and the new timer works fine. But I see two issues . First, the item is rather pricey. In fact I could have bought two electronic 2h timers for less money than I paid for this spring based timer. Second, the knob cannot be pushed all the way on the timer shaft that creates a sizable gap. Though I am not sure if it is a defect or a "design" . If it is the latter it has to be the pretty bad one.
