I need a snap-action thermostat that closes a contact on temperature rise.

Trip Point: -10 degC +- 5 degC, not necessarily adjustable
Hysteresis: ~5 degC
Current rating: 100mAdc
Size: Tiny, and light. It is going to be lofted by a balloon.

I would prefer a Klixon type. I'll make an electronic circuit only if I have to...

 

Sylvania - SB605G1H



No information.
This might be a good type

edit:

I really looked hard.
Under 20C is tough to find.

 

Thanks, I may just have to go the chip route. I'm looking at an LM26, which can be bought from DigiKey pre-programmed to either -25C or 0C.
