I am using this to turn a cooling fan on (and off).
The switch is normally open (off).
I simply taped it to a surface and it worked!
When it senses temps over 40°C the switch closes (turns on) and turns on a fan I wired it to.
When the fan cools the surface the sensor/switch is on, the switch opens and the fan turns off. I left it hooked up for hours and it went merrily along, turning the fan on and off automatically. I put a couple layers of electrical tape over the sensor so the switch wouldn't cool before the surface it was on.
I used an infrared laser thermometer to read the temps and it switches exactly where it claims to.
The "head" is a solid metal "lozenge" that appears to be very durable.
Oh, it arrived very quickly. I have Prime so I think it showed up in 2 days.
Pretty cool for less than a dollar per switch.
Great for the price, I taped one to a small refrigerators compressor to turn on a 4" 12v. fan powered by a wall wart. It helps cool it. Works very well. Thanks.
I bought these to control a fan inside a 12X12 plastic box. I have a power supply and a printed cuirit board mounted inside. The boxes will be outside during the holiday seasons. Living in Florida the temperature gets a little hot. Didnot want to burn up boards. Havent had a chance to test them yet, but seems to working during testing.
I bought these to control computer style fans that cool my Ham radios in my shack. They kick on around 104F and shut off as soon as it gets back below that temp. I have been using them for several weeks now and they work great for my purpose. I only give them 4 stars due to having 2 bad ones in the package.
Great thermal switch. Used to engage a blower over a fuel rail of turbo engine to keep gas below 40 C with excellent results. Blower runs with 4 A and after a full year installed the switch keep working as new.
Recommend.
