Thermal Switch Controls Auxiliary Cooling Fans

Thermal Switch (thermostat) specs:  2570F108-665 (Close 105°F, Open 95°F)

Thermal switches used in conjunction with cooling fans are useful in protecting electronics.  R.B. from Baton Rouge, LA  used on of our sealed temperature switches to protect the TV in his motorhome.  He drives a class C motorhome which has a TV located in an overhead cabinet.  “The last TV I put up there had a meltdown,” he says.

Credit to Frankie ValentineAfter receiving our switch, he “tested the on/off setting to see if your specs were accurate-they were;” a prudent step.  R.B. installed the thermal switch in the case at the top most area of the TV and wired it to auxiliary cooling fans.  The switch turns the fans on at 105°F and off at 95°F.  He reports that “the switch is working as described.”

Our temperature switches work by using a bimetal disc. The bimetal disc in the switch reacts to heat, and opens or closes a set of contacts based on what the ambient temperature is. This is works because the different metals in the disc react to heat in different ways, which causes the disc to bend.
