A detail of the switch operation. When activated, the metal disks on the right press on the little white knobs on the left. This cuts the power. The black box with the white knobs looks pretty neat inside as well. A surprising design in its complexity, but using thermistors would require the use of some kind of transistors, meaning that his metal-plastic setup is cheaper.
