Looking for Thermal Switches

[Rawmeat]

Hopeing someone here can help me out.. Ive been searching all over the net for a company who makes small thermally activated swiches.. open circut untill 50c then closed untill 35c. Its a very simple device but I can not for the life of me find a place that sells them. All I can find are heavy duty spacecraft/military ones or auto ones.

Hell I dont even need the product itself if anyone has the diagram for this circut Ill make it myself. Speaking of diagrams I am also looking for the diagram to a thermaly controlled resistor via thermistor if anyone knows where to find this I would be a happy man! (alot like the TT smartfans work), temp rises.. fan spins faster etc etc)

Have you tried the surplus outlets, like All Electronics (www.allcorp.com (http://www.allcorp.com))? They often have things like the thermally controlled switch you mentioned.
