The switch on the rice cooker or electric kettle is locked after being pressed. However, after heating to the specified condition, the magnet or bimetal piece that locks the switch state acts to reset the switch and cut off the power supply (the rice cooker is converted to the heat preservation state) , may not meet the "reset after power off" requirement.
Reset after a power outage, that is, the locking mechanism should work related to the power supply. The finished product does not seem to have this, because this requirement can be achieved by using a circuit composed of a general push button switch and a relay; but if only one relay (or contactor) is used, one of the relays (or contactors) must be used. A set of normally open contacts is used to control the power supply of the working coil of the relay (contactor). The relay scale is used as a switch button. After pressing the scale, the contacts of the relay control coil are closed, the coil is energized, and the relay remains closed ( Self-locking), the remaining contacts control other circuits; when the power is cut off, the relay is cut off immediately, and the scale iron is reset, which is equivalent to the button reset. You need to press the relay scale iron again before the power can be turned on again. This relay is equivalent to a live lock
