Intermatic T104M Mechanical Time Switch Mechanism Only

Exact replacement for my old poolTimer. 10 minutes to hook it it and get it running. Works as intended.

Great product, easy to install. I saved myself a lot of money buying this replacement part and installing it myself. Watched a few videos and took a before picture of the wiring so I could easily put the wires back into the correct place. My pool is running great and the timer pins turn it on and off for me.

The T104M boasts a sturdy metal construction that exudes quality and durability. The compact design (6.5" x 4.5" x 2.25") makes it ideal for use in tight spaces, such as basements or crawlspaces. The time switch's ruggedness and weather-resistance ensure reliable operation even in harsh environments.The T104M features a simple, intuitive mechanical mechanism that's easy to set and adjust. The on/off toggle switch is smooth and requires minimal force to operate, reducing wear and tear over time. The built-in clock mechanism allows for precise timing (15-minute increments) and has a reliable locking system to prevent accidental changes - if needed.I found the T104M to be impressively accurate with the time, with an average deviation ofonly 1-2 minutes from the set time. This level of precision is essential for controlling pool pumps, water heaters etc it ensures consistent on/off cycles and energy efficiency.The Intermatic T104M Mechanical Time Switch is a reliable, easy-to-use device that excels in terms of accuracy, power handling, and durability. Its rugged construction and simple mechanical mechanism make it an excellent and the one I replaced was well over 20 years old.

easy to install and working as needed

This is going to be an unusual review of this item. First off, I purchased this as an exact replacement of the original pool timer that was probably there since the pool was built. We bought this home from a previous owner 14 years ago and though I don't know exactly when the pool was built originally, I have every reason to believe the old part was the original timer. That says a lot about its quality and reliability. But it did ultimately stopped working.So, the new replacement came. It is literally a snap to remove the old one and install the new one (exact same model). The snap/clip that holds it in place is a one handed operation in less time that it would take to exhale and inhale a single breath. By the way, as a tip, after making sure the power is completely turned off from the breaker, take a photo of the original wiring arrangements before removing. One Philips screw driver, and off with the wires. Putting them back in took just a few minutes. The pump turned on.And this is where I pivot to customer service. There was something wrong with how the timer dial indicator was moving. The clock was running counter clockwise. I called the manufacturer's product support who advised that I return the item because it had to be defective for the clock to behave that way. I contacted Amazon thru the usual return order process (all done online). A quick response gave instructions on how and where to return it (Kohl's nearby will repack and shipped the old item for free). A replacement was expected to be shipped in a little over a week. Meanwhile, the pool pump was running and I thought I'd keep it running and will manually shut it off and back on as I had been doing the past two weeks anyhow (with the old timer).Well, lo and behold, by early evening it turned off! That led me to re-examine or re-analyze the timer dial movement. I was mistaken. I totally misread how it was moving. I thought I'd wait till the following morning to call off the shipment of the replacement item and it would confirm by morning, for sure, if the pump will automatically turn on. It id!!Early his morning I got an email from Amazon that there was good news. The replacement will get here in three days. Oh no! I didn't expect Amazon to ship the item until they got the old one back. So now, egg on my face, I went to cancel the item.This review is about two things. This timer is one solid performer. Remember it took all those many years (power outages, hurricanes, one pump change) when it finally gave up; though not entirely. The auto timer did fail but I was able to manually make it work. The manufacturer's product support was responsive (although the product turned out to be all right). Then, this proves once again that Amazon has no equal. Bravo to customer support!!!

Arrived on time.

Quick delivery! Easy to install! So nice to not have to manually turn on my pool pump again since hurricane Milton!!!

The product arrived in the original packaging without external damage or soiling. It was, as well, unused. It was a replacement for an older identical model that had a failed clock module. Given the small difference in price between replacing the entire unit, I opted for a total replacement instead. If I didn't, I'd probably be buying another before much longer, so it was cheap insurance to just do it now.All kudos belong to the seller.Amazon OTOH, would get less than 5 stars. Per usual, for about 90% of my deliveries from this facility, the delivery was not made within the committed time. Many times delivery time drives which product I choose, mostly to my utter frustration.The delay was minor, this time. It isn't most of the time.DO BETTER OR STOP OFFERING DELIVERY TIMES YOU CAN'T MEET AMAZON!
