The ceramic snap-action automatic reset temperature controller is primarily used for temperature control in electrical appliances such as air conditioners, water dispensers, electric kettles, rice cookers, sterilizers, coffee makers, and electric steamers. Its working principle involves using a disk-shaped bimetallic strip as a temperature sensing element. When the temperature reaches a certain point, the disk snaps, causing the contact to actuate quickly; when the temperature drops to a certain level, the disk resets, and the contact returns to its original state, thereby achieving the purpose of opening or closing the circuit. It features a small size, light weight, non-arcing, high reliability, long lifespan, and minimal radio frequency interference.
