How Does Micro Switch Control Electric Kettle

The water temperature rises when the electric kettle is energized to generate heat. After the water boils, the kettle automatically cuts off power to save energy. 


Electric heating principle & micro switch

The principle is straightforward. The electric heating tube of the electric kettle is connected in series with the Microswitch and connected to the AC220V power base. People usually install the electric heating tube at the bottom of the pot and our unionwell Microswitch at the upper end of the handle. Then they install a metal piece in front of the Microswitch. There is a square hole in front of the metal piece. The square hole leads to the inside of the pot. 

When the water vapour flows out of the square hole, the metal piece is deformed by heat, and the lever opens the Microswitch To achieve the purpose of automatic power off.
