KatzDoes anyone know how electric blankets work? It has been said in this list that the thermostat is in the blanket itself, and I would tend to believe that because the temperature regulation seems to work (ie if its set low, it doesn't stay on alot). However, the control box with the knob on it seems to be a thermostat, it clicks on and off with temperature, and there doesn't seem to be any thermostat in the blanket itself that I can see. If the thermostat is in the blanket, what is it like and how does it make the control box click on and off? If it is not, and the thermostat is in the control box, how does it regulate the temperature of the blanket? Alan PS, I am pretty sure there is no thermister or any other electronic type components here, these things seem to be mechanical. -------
