This I bought for an outside socket I have fitted. I have placed it along side the socket (inside as it is not IP protected). I have installed it solely for the purpose of being able to time the outside light around the garden and water feature. With the larger did for manually setting the times on / off and the centre clock is great for adjusting the actual current time to a fine adjustment, so you get he time 100% right and easily too. I know the original purpose is for an emersion heater but this works well in my situation and is sunken into the wall so to not be knocked. It also have a cover for added protection form knocks and little fingers too. This is easily removed and refitted via a simple click on / off. Fitting I would recommend a qualified electrician as electricity is a killer. Review: It's a tight fit! - Even when mounted on 55mm deep x 90mm x 120mm die cast box as a fireproof mounting it's difficult to form 6 x 2.5 mm sq. flex conductors (for 3kw immersion heater) to the 3 input and 3 output terminals, tip. fit ring crimps on first. also separating front plate from the back box requires the grip of alligator, the first time I opened it up I felt something would break. Relieved when it didn't and had forced everything back together, just. Working well tho' and the mechanical simplicity when setting ON / OFF is good with the aid of small pointy stick. Saving around 3kwh a day now so worth the effort. ## Features - 16A Immersion Heater Timer ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00KGAAVIU | | Best Sellers Rank | 45,835 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 2,260 in Lab Instruments & Equipment | | Brand | lowenergysupermaket | | Brand Name | lowenergysupermaket | | Colour | White | | Country Of Origin | China | | Customer Reviews | 4.1 out of 5 stars 144 Reviews | | Item Dimensions D x W x H | 52D x 7.5W x 5.2H centimetres | | Item Weight | 0.04 Kilograms | | Item weight | 0.04 Kilograms | | Manufacturer | Lowenergie | | Material | Metal | | Material Type | Metal | | Number of settings | 4 | | Product dimensions | 52D x 7.5W x 5.2H centimetres | | Screen Size | 75 Millimetres | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 799493545463 | | Unit Count | 1.0 count | ## Product Details - **Colour:** White - **Brand:** lowenergysupermaket - **Material:** Plastic - **Product dimensions:** 52D x 7.5W x 5.2H centimetres - **Item weight:** 0.04 Kilograms ## Images ![Lowenergie 16A Duty Mechanical Time switch Light Segmental Timer, hydroponics grow lighting - Image 1](https://m.media-amazon.com/images/I/617gPxdGruL.jpg) ![Lowenergie 16A Duty Mechanical Time switch Light Segmental Timer, hydroponics grow lighting - Image 2](https://m.media-amazon.com/images/I/61GTKYL2U-L.jpg) ![Lowenergie 16A Duty Mechanical Time switch Light Segmental Timer, hydroponics grow lighting - Image 3](https://m.media-amazon.com/images/I/71oDTZg28sL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple to use an simple to set on / off time and as it the clock time. *by F***S on 9 February 2017* [...] I can assure you will make me happy and my review helpful.
