Abstract
A device for temperature regulation has a contact housing which is provided ith a movable contact spring for breaking a circuit and on which a fastening flange is fastened. Furthermore, there is a tube of low thermal expansion, in which a bar with a high coefficient of thermal expansion is arranged so as to be longitudinally displaceable. That end of the tube located on the same side as the switch is supported in a concave receptacle arched in the direction of the contact housing.
