Working Principle

The adjustable temperature control switch employs dual metal sheets as thermal sensitivity reaction components. When product temperature increases, heat transfers to the bimetal sheets, causing movement at the set action temperature to open or close contacts. When temperature drops to the reset temperature setting, the bimetal sheets restore to their original state, completing or breaking the circuit to maintain temperature within a constant range.
