Problems solved by technology
The problem with this warped arm steam thermostat is that the switching between the normally closed contact and the normally open contact depends on a metal temperature-sensing contact piece. When the metal temperature-sensing contact piece is heated, the normally closed contact is disconnected and the normally open contact The two normally open contacts remain closed after the metal temperature-sensing contact piece cools down and resets.
After the power is cut off, when the user leaves the electric kettle for a certain distance, he cannot know the working status of the kettle at this time. Failure of the controller can easily lead to continuous heating and fire
