  • Electric toaster
    Publication number: 20020002910
    Abstract: In an otherwise well-known electric pop-up toaster, an auxiliary power switch is provided and is arranged to be opened by a timer after each toasting cycle. This ensures, in contrast to the well-known toaster arrangements, that power is interrupted to heating elements even if a carriage supporting slices of toast fails to move up at the end of a toasting cycle.
