since there doesn't seem to be a reset thermal switch that can be mounted directly on board, does anyone have a cutoff circuit to accomplish the same thing?
must be around 55-60C, carry 2A of DC voltage and have almost zero resistance.
must withstand oven reflow temperatures.
must be normally closed and open when cutoff temperature is reached and closes again when temp falls.
this will be used on a LED circuit board mounted on a heatsink and the heatsink should not go above 55C so it is not too hot to touch.
thanks

 

hi 44,

the wythermostat is a possibility.
i need to stay the size of TO220 or smaller.
thanks a million.

look at www.cs-thermo.de
it's in Germany but sold all over the world.
