Stap 13

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.
