Intermatic T104R Mechanical Timer Switch, 208-277V DPST, Type 3R

We're in the lightning capital of the country so we often get calls from clients whose digital timers are fried. We recommend these mechanical timers and they last and last. Easy to install and super simple for the clients to adjust their times by themselves. We never go wrong with Intermatic Timers.

Perfect replacement. I did the research and bought the correct part. Installation was easy. I did have to extend a wire to reach the other timer and to reach the breaker. Working great so far.

We have higher rate hours with our electric company and this helps tremendously. We had a professional install and he also commented it was a spot on device. Easy to set and change settings! Great price compared to local box stores as well! You can basically set it and forget it!

I have bought two of these timers. And they both work great for my pool pump and vacuum pump. I bought the cheaper one for around $59 and it did not work properly. Would not turn the pump on. This is a good brand I recommend it.

It is exactly what I needed.

Why did you pick this product vs others?: This was a perfect replacement for my old Intermatic timer. The old one has been in use for at least 10 years, and finally gave up. It was used to turn the pool lights on and off. The pump is on a separate timer. It was a super easy swap out. I unscrewed the wires, making sure to be able to identify them when I reconnected them to the new timer. The old one pops out by pressing a retaining tab inside the enclosure. The new one slides right into place. I reconnected the wires and was back in business in 10 minutes. It is way easier to replace just the internals instead of the entire box. I expect this one will last another 10 years. Intermatic has a great reputation for quality and longevity. Pro tip...make sure you buy the correct timer for the voltage you are using. They come in 240 volt and 120 models. Make sure you order the right voltage for your application...I highly recommend this as a great replacement timer.

This was a perfect replacement for my old, failed mechanism. Installation could not have been easier.

I would give this 5 stars for how it runs - which is great now that it is has been running great for 2 weeks so far. The timer is exactly what I expected and easy to replace. The housing wasnt even needed as I was able to disconnect the wiring and remove the timer unit from the housing and insert that into the housing of my old timer (same model) and reconnect the wiring. SImple! Just make sure to snap it correctly into place so it does not sit loosley in the housing. The reason I took back a star is because after installing it, it did not work. It would not trip the switch to on or off even though the power was running through it ok. I could manually turn it on and off and the timer wheel would travel correctly but it would stall at the timer pin and just couldnt trip the switch. I read other reviews about this model and saw a post where they recommended just to return it and buy a better timer. I'm glad I don't give up that easy. This thing was brand new so I removed the unit from the housing once again and noticed there is tiny amounts of grease at all the hinge joints that connect the manual switch lever to the timer wheel. With the timer unit was still disconnected I quickly moved the switch on & off repeatedly about 10-15 times to get the grease into the joints to free up the motion. I reinstalled the timer unit and Voila. It worked like a boss. If I hadn't known to try this, it would have been back in the box being returned as a DOA unit.

A direct no-trouble replacement in a unit that died maybe a decade after installation. This timer works non-stop for half of the year and is used for a 220v pool motor. It’s been more than a year that it’s in place and seems ready for many more.

Thanks to time-of-use electricity pricing, it's no longer reasonable or affordable to run the pool pump all day to keep the water circulated, clear, and algae free. No, it necessitates an evening run to the pool shed to fire up the pump for 12 glorious hours of lowest-rate power, and if you miss the alarm, 2-4 more hours of much more expensive power. Plus, I have other urgent priorities when I first wake up, and the sound of running water ensures that first things happen first. Since I prefer dry feet and not much moving about when I first wake, heading to the pool shed through dewy grass to turn off the pump and keep some cash in my pocket simply doesn't appeal to me. Enter the timer. It's quite challenging to find a 240v timer here in North America, but between Intermatic making one, Amazon selling it, and FedEx delivering to my door, it has been accomplished! The wiring diagram is a little difficult to comprehend but once you understand what it's showing you, it's simple and straightforward to hook up. The weatherproof box means it can be mounted outside but my handy pool shed ensures both my pump and timer are dry, save perhaps catastrophic failure of pump seals. As an added bonus, the timer keeps time. The timer on/off adjusters are a little finicky to use, but that may have more to do with my sausage-sized fingers. If, like me, your hands and fingers are large, you may want a 10 year old around to help put them on. If you can't find one, I hear there are loads at your local skate park. In a nutshell, I'm banking on nothing short of a direct lightning strike will cause me to have to make a dewy run to the pool shed ever again.

Fonctionne très bien

funcionó de maravilla y quedó al cien

Have this timer hooked up for a wintertime automotive block heater outlet. Keeps time very well and works great. I opted for this particular timer due to the "Intermatic" brand name which is tried and true. I was looking at the digital timers on Amazon but chose this mechanical timer mostly due to the fact that we have various numerable power outages and interruptions because of our rural location. Going outside to mess with a digital timer and reset everything at -30c pushing buttons and going through various menus? Screw that! A simple spin of the timer dial on this timer to reset to the correct time and it's good to go again.
