Rice cooker lid lock features position sensing reed switches

Rice cooker lid lock features position sensing reed switches
Electric rice cookers are popular appliances that are used for cooking rice. These are pressure cookers that rely on a properly sealed compartment which maintains a high pressure. The pressure built up within the rice cooker compartment can be high enough to blow open the cooker lid if the lid is not properly locked in place when closed. The position sensing lid lock ensures that the lid is securely locked in place.
