THERMAL SWITCH, N/O 30C 03EN35T044(20/30) By MICROTHERM

I purchased this last year to switch on an extractor fan when the apex of the greenhouse reached thirty degrees, it works perfectly allowing the battery to be used much more efficiently. Eventually I'll find somewhere to put a solar panel and charge the battery when the fan is not in use.My only bugbear is I'd like a switch that operates at 25C but this one works perfectly.

After purchasing a new TV cabinet there was a lack of cooling, and found it got quite warm with the front doors closed (Have a back on it as it gathers too much dust)Bought these sensors, rigged up through a 12V Power supply from local store, as well as a couple of Computer cooling fans, an d some LED's to show when activated.Once wired - plugged it, and turned all the toys on, and as if by magic - a subtle click, the fans started up, and the LED's came on.These are perfect sensors, not to sensitive - recommended !

Purchased to turn a cooling fan on when my son's X-Box reaches 30 C, as it is fitted inside a cabinate under the TV. Works well, keeps the X-box cool, and turns the fan off when cooled down.
