| [* black] The toaster has been deconstructed! | |
| [* black] To completely remove the front panel, remove the plastic handle on the lever used to pull down the toaster. However, this is quite difficult, must be glued back on, and isn't necessary to reach the working parts of the toaster. | |
| [* icon_note] The spring-loaded "toasting lever" used to start the toaster closes the circuit using a dual switch in the rear. | |
| - | [* icon_note] The timing mechanism consists of a physical latch engaged by the "toasting lever," an induction coil (visible in first figure), and a potentiometer. |
| - | [* black] When the coil has current running through it, it becomes magnetized, causing it to attract the steel latch. |
| - | [* black] At some point, the latch is pulled far enough to release, causing the toast to pop up and breaking the circuit. |
| - | [* black] The lever that controls cook time is connected to a potentiometer which alters the current flowing through the electromagnet, causing it to take different amounts of time to release the latch. |
| + | [* icon_note] The timing mechanism consists of a physical latch engaged by the "toasting lever," an induction coil (visible in the first picture), a cook-time adjustment lever, and a bimetallic strip. |
| + | [* black] When exposed to the heat of the toaster, the bimetallic strip bends, pushing a plunger connected to a switch. |
| + | [* black] When the strip has bent far enough the plunger closes a switch, causing current to flow through the coil. The magnetized coil will then pull the latch open. |
| + | [* black] This simultaneously turns causes the toast to pop up by releasing the spring loaded toasting lever, and turning the toaster off by breaking the circuit connecting it to the power source. |
| + | [* black] The cook-time adjustment lever changes the distance between the plunger and the switch. The further the distance, the more the strip has to bend, and so the hotter the toaster will get before it turns off. |
