The document describes the various internal parts of a toaster, including the lever, plastic tab, contacts, metal tab, electromagnet, springs, self-positioning slot, and printed circuit board. The lever is connected to the handle on the outside of the shell. When the lever is pushed down, the plastic tab closes the electrical contacts to start the toasting process. The electromagnet then attracts and holds the metal tab in place during toasting. Springs return the lever and parts to their original position once toasting is complete.
