Fixed the ON of our OLD Intermatic
Fits our old Intermatic wayer heater timer. The Go trip was all we really needed. We have an old Intermatic timer on our water heater. The GO trip from this works great.

Wow, just wow.
So I bought a house last year and it came with this weird contraption in the garage attached to the water heater that I didn't know what it was for. Low and be hold I saw a YouTube video about it and was like 'holy cow, is that what's in my garage?' I immediately went out to check and Yes, it is, however, I don't have any of the little clip things that control when the hot water Heater turns on and off. After a little bit of research I discovered these clips and immediately ordered them. Shipping was super fast and were incredibly easy to install, you just screw them on at the times you want your water heater to activate. I specifically chose off hours over night when electricity is at its cheapest. I'll be doing a comparison on my electric bill to see how big a difference it makes. I looked at last month, and my power company does an analysis of usage, and water heaters usually are a third of a home's monthly usage. If that's the case, my Water heater was boiling that water continuously, I should see a significant difference in my next bill. Fingers crossed! Update, electric bill already is showing a decreasing trend 2 weeks in!

Need pliers to tighten them up
They are very easy to use but frequently fall off but have a good color. Poor quality and not very well at doing the job.

Durable Timer Switch Trips
Used on a pool timer. Durable. Long lasting especially since used in an outdoor timer and the Florida humidity. Definitely recommend.

Functional
Bought these to replace the originals on my pool timer. They work well and fit fine. I do wish would come up with an alternative to the tiny screws- perhaps one that clips.

Just what was needed
Fit mechanical timer. Allows for multiple on and off times. Slide right on and tighten down.
