The 220V power switch and the thermal switch are connected in series and then connected to the electric heating tube. Plug in the power and press the switch. The power supply flows through the thermal switch and reaches the electric heating tube. When the temperature in the kettle rises to the action value of the thermal switch, the spring in the switch will rebound due to thermal deformation, so that the contact will be separated and the power supply will be cut off.
Electric kettle is an electric appliance with intelligent steam induction control, overheating protection, automatic power-off when water is turned on, dry burning prevention and power-off, and rapid boiling.
