Toaster works is like this:

· When you press the operating handle, plastic rod pressure contacts, circuit board power.

· Current flows directly through the contacts to the Nickel-chromium-iron alloy wire and began baking bread.

· By transistors, resistors and capacitors composed of a simple circuit opens, the electromagnet power.

· Sheet metal electromagnetic iron handles, so as to keep the bread in the toaster.

· Simple circuits to the timer function. Charging capacitor resistance when it reaches a certain voltage, it will cut off the current to the electromagnet. Spring two slices of bread pop up at once.

· Meanwhile, rises in the plastic rods, cut off the toaster's power.

In this toaster, degree of control burnt component is just a variable resistor. Change resistor capacitor charging speed, so as to control the timer length of time to wait before releasing electro-magnet.

Any toaster applied the basic principle is very simple. Bread toaster using infrared radiation heating. Into the bread, and then when you see the coils turn red, the coil is in the infrared radiation, the radiation surface can gradually make the bread dry and zoom.

Toaster produces infrared radiation is the most common way to use wrapped around MICA Nickel-chromium-iron alloy wire, Nickel-chromium-iron alloy wire is an alloy of nickel and chromium. It can become a good heat because it has two features:

1 · Compared with materials such as copper, Nickel-chromium-iron alloy wire resistance is quite high, even for a short period is enough to have a great deal of heat resistance.

2 · Nickel-chromium-iron alloy heating without oxidation. Wire heat in the toaster will quickly corrode.

Simplest toaster needs two pieces of MICA wound Nickel-chromium-iron alloy wire, they are placed in parallel, forming about 2.5 cm of Groove in the Middle, Nickel-chromium-iron alloy wire directly connected to the plug.
