Thermo switch to control fan...

Hi -

Question about a thermo-switch to control a simple fan. Is there an adjustable thermo switch that can be set to turn on a fan when the temperature reaches, say - 90 degrees F?

The application would be a car battery powered fan (inside the vehicle) that would kick on when the car temp reached a preset threshold.

hi,
You can buy a range of normally open or closed 'fixed ' temperature switches.

EDIT
: look here for examples

Alternatives...

These look pretty fancy (and some require shipment from Europe... :) - could the same be achieved by employing a house thermostat - like an inexpensive programmable thermostat to control the on/off power to the fan?!

THanks in advance -

Yes, but your wife will be really mad when she goes to turn on the A/C, and the thermostat is missing!

They're not fancy, they're basic bimetallic strip thermostats, no fancy programmable microcontroller, just connect in series with the fan and it'll work.

Yes, you can.

In fact the Google search I did found loads of them. I deliberately avoided them because I thought you wanted something more simple and robust.
