Customer Reviews for Intermatic T100 Series 40 Amp 208-277V DPST 24 Hour Mechanical Time Switch Mechanism

This is an exact replacement for a timer installed in 1984. It was a very install.

Great timer for our pool

Exactly what I needed to replace my non-working timer!

Easy to install once I followed the YouTube how to. Very happy I didn’t have to pay for installation.

I bought this for the secondary pump but the wires were not long enough to wire the timer to the main pump timer to keep it in sync. I had to splice longer wires but now it is working fine.

Great timer. Just what I needed for my job application

This was the last one on the shelf. It looked like it had been around awhile. It was obviously a return that didn't work after my installer installed it. Had to return it.

Solid Contraction that Will Last!

The unit is solid and functions well. It snapped right into an existing box. The install instructions were clear and concise. Well made unit I expect will last a long time. There are similar looking units on the market that are not as robust, but this one is well made.

Wiring diagram didn’t make sense so it cost me $140 to have a pro install what should have tanker me 15 mins.

Replaced the previous one perfectly

The timer was really easy to replace to get our pool filter back on schedule. Do your homework and make sure you buy the right one. Turn off the power before installing. Easy DIY.

Straight swap from my old pool timer but this one is much quieter.

Needed to replace a unit that was over 10 years old. Swapped out with the original. Was a quick fix. Used existing box and just replaced internals. Fast swap. Took about 15 minutes. Works as intended.

Perfect replacement, easy to install. Easy DIY project that saves a lot vs. having your pool contractor do it.

Very easy to install. If you dont know Electrical wiring, i recommend taking a picture of what you currently have installed. And replace the same wiring.

On the shelf product a plus. Easy to read instructions and wiring diagram to follow. Change out replacement was quick in about 15 minutes. Remember to Alway following the safety instructions.

I bought this even though it isn't an exact replacement for my water heater timer (volts and amps match). It works great, and as far as I can tell, the only difference between this one and the water heater version is that the switch on this one isn't long enough to extend through the door of the timer's housing. On my previous timer, the plastic part that contacts the on-off tabs broke, and hence the replacement. This is the first one I've had to replace, even after using several timers for 20+ years.

Great item,perfect fit.

This is a quality product. Over the years I have replaced a few. It operates my swimming pool pump and it is not uncommon to have to replace it once it is over five years old. It is very simple to replace by the homeowner, as long as the homeowner has good common sense and reads the directions. I have always had good luck with Intermatic timers and will always keep purchasing them for my timer needs.

Part for part swap so it was an easy fix

I brought a open boxed timer and when I installed it it wouldn’t work. I had to return it and buy a unopened timer from Leslie’s

Part was a direct replacement. Works. Now, I wonder if it will last 15-20 years like my last one. Time will tell.
