This is sufficient to operate the carriage and raise the toasted bread from the toaster. This movement is very small - on the order of thousandths of an inch - but a mechanical linkage multiplies this movement approximately 175 times. When the thermostat opens, the elements cool, and the center element wire contracts. The toast is raised only when it is properly toasted no sooner and no later. Inside, the Radiant Control thermostat monitors the heat radiated (not conducted) from the outer surface of the bread, which is directly proportional to its color change. The weight of the bread activates the heating elements, causing the center wire to lengthen microscopically and the bread to be carried into the toaster under its own weight.
