Working Principle of Normally Closed KSD-01F Thermal Protector
KSD-01F temperature control switch adopts T0-220 package form, sudden jump type, single-pole/single-throw contact point of 100% conduction structure, when the external temperature is too high, it will be transferred to the corrected bimetallic strip Act quickly to cut off or connect the circuit (normally closed or normally open). When the temperature drops to the reset temperature, the bimetallic strip will quickly reset again, repeating the work to ensure the safety of the product temperature protection.
