Bimetal Thermal Protector is a temperature control switch that uses bimetal as a temperature sensing element. When the appliance is working normally, the bimetal strip is in a free state and the contacts are in a connected state. When the temperature rises to the operating temperature point, the bimetal element is heated to generate internal stress and quickly operates, opening the contacts and cutting off/connecting the circuit, thereby playing a thermal protection role. When the ambient temperature drops to the reset temperature of the protector, the contacts will close again to connect the circuit.

I’m looking KSD9700 temperature switches and came across this type which warns against shorts and instructs you to use a provided plastic sleeve to prevent this.

I’d like to understand exactly what could short to what. I wouldn’t have thought that the outer metal shell would be conductive to the leads, but is that actually what this warning is about? If not, what are they warning against? YES

Aside from the risk of a short causing a problem, I would ideally want the metal case to be directly on the object whose temperature is being measured for the fastest response without any insulating effect of the plastic.

Process of Custom Thermal Protector NO / NC (KSD9700 / Seki) Temperature Control Switch

②: Submit preliminary plan for feasibility analysis of customer request;
③: Financial accounting cost;
④: Technical preparation experiment and design simulation;
⑤: Procurement investigation of various material costs;
⑥: Production knows product processing flow and staffing;
⑦: Quality evaluation and inspection process;

Descripció del producte

What’s the difference between N/C and N/O
Normally Closed: When the temperature falls to the reset temperature, the thermostat contact can be connected again.
Normally Open: When the temperature falls to the reset temperature, the thermostat contact can be disconnected again.
