• Now that we know how to dissaseble the toaster, it's valuable to learn a little bit about how it functions:
• The toaster constantly receives power when it's plugged in, but the electrical circuit remains inactive until you push down the handle.
• Pushing down the handle causes two switches to close, completing the circuit and activating the toaster's power source.
• The circuit breaks when a certain power level is reached in the timing chip on the circuit board. This signal weakens the electromagnet, releasing the handle and popping up the bread trays.
• A potentiometer, linked to the control knob on the front of the device, regulates power flow to the chip.
• Setting to maximum (level seven) restricts the power flow, prolonging toasting. On the other hand, choosing cancel reduces resistance, quickly ejecting the toast.
