During a scavenge hunt in GoodWill, we decided to take apart a toaster for knolling project. Questions we had before we took it apart?
How does a toaster switch between on and off?
Is there any heating sensor controlling the temperature inside?
How does the toaster keep the slider down?
After we took it apart, we found out that by pressing the slider down and stretching the spring side, AC power is then connected to the toaster. Once the power is connected, the heating elements inside are immediately switch on. Couples of resistors are found inside to keep the temperature from going too high. The electromagnet is the one that keeps the slider down. And the only logistic part inside is the timer. It cuts the power from the electromagnet, then release the slider and stops heating. Spring force released, pushes toasted breads into the air. Bang. Breakfast.
