The kettle switch is characterized in that after the kettle switch is pressed and powered on, the kettle switch can jump to power off only after water is boiled, and can not automatically reset and powered on after jumping, so that the execution module only needs a few seconds of instant suction force or repulsion force to act on the kettle switch to enable the kettle switch to be pressed or jumped, and the direct-current voltage of the hollow coil in the execution module is also instant and does not need to be powered on and maintained all the time.
