Thermal switch

eRiCdWoNg · 11th May 2004, 04:28 PM

I'm trying to design a cooling mechanism for an amplifier (pa rack and car audio), what I need it to do, is turn on above 170 degrees F and off below this temperture. Im not sure what this is called, is it a thermal switch? Any help would be greatly appreciated.

That's what you need, but they're pretty tough to find. Try AllElectronics

Farnell and RS sell them - for example: http://uk.farnell.com/jsp/search/sea...0000~081038000

(if the link fails, goto farnell.co.uk, click S-U, then scroll to Switches. Then scroll down to Thermal)

I think that Farnell sell in the US, possibly under the Newark brand, if memory serves... I'm sure Digikey will hold some too...
