A thermostat for refrigerators with a constant switching-on and adjustable switching-off temperature uses only one spring, the switching-on and switching-off temperatures being determined by the position of components of the omega switching system. The switching-on temperature of the thermostat and the difference between the switching-on and switching-off temperatures can be adjusted by means of setting screws, whereas the absolute value of the switching-off temperature can be adjusted by a cam.
