## Customer Reviews

### ⭐⭐⭐⭐⭐ Used this to power two DC ceiling fans in my greenhouse
*by B***K on March 21, 2013*

I have a small 20 Watt 12V DC solar panel and two 6 Watt ceiling fans for my greenhouse and wanted to figure out how to turn the fans on when an internal temperature threshold was crossed. This switch works perfectly to facilitate that goal. I used 12 AWG wire and female connectors from Menards to make the connection from the battery to the switch then the same to connect the fans. I positioned the switch at waist height to make certain the majority of the greenhouse was at or about 80 degrees when the switch activates. So far, it all works perfectly. When the sun is out, the greenhouse heats up and the fans go on as soon as the internal temperature reaches 80 degrees. The 20 watt solar panel is more than enough to power the two ceiling fans plus a humidity exhaust fan made from a recycled 120mm computer exhaust fan. As soon as the sun goes down, or the internal greenhouse temperature goes below 65, the fans shut off. I could not be happier with how well this switch works.

### ⭐⭐⭐⭐⭐ Works great! Used for about a month now
*by K***Y on January 7, 2018*

Works great! Used for about a month now. Easy install, reliable so far. I believe that this little switch was a major upgrade to the efficiency of my forced-air wood-burning furnace. I swapped this switch with the old one (On at 120 F Off at 90 F) and the fan blows warm air 8-15 minutes earlier than before, and runs longer at a much lower temperature. Now, I don't have to "over-stoke" just to keep the fan running. This saves me a lot of lost heat and firewood. But, as with all things wood-burning--it's a tough variable to measure.

### ⭐⭐⭐ Great while it lasted!
*by T***Y on April 27, 2020*

Worked great for about a month using to turn on and off my greenhouse solar powered fan. Failed and I had to hook straight up so the fan is just on when the sun comes up weather its warm in there or not. I may possibly be getting another one of these but will try to do a little research first to see if the way I had it hooked up could be tge cause of the failure.
