Another unique point is that when the heating wire cools and contracts, a mechanical chain reaction occurs in which the bread is lifted up. The mechanism that the metal plate is designed to turn off the switch. Specifically, inside the toaster, a bimetal that 'bonds two alloy thin plates with different coefficients of thermal expansion and bends the metal according to the difference in elongation of each alloy' is installed, and it bends due to heat dissipation from the toaster.
