A KST temperature controller is a bimetallic thermostat used for precise temperature regulation. It works using a bimetallic disc that responds to temperature changes. When the set temperature is reached, the bimetal disc opens or closes the electrical circuit, controlling the heating or cooling system. These temperature controllers are used in many appliances, heating systems and industrial equipment because they are simple, reliable and cost-effective. KST thermostats are available in a range of settings and configurations, offering options like automatic reset, manual reset or one-time thermal cutoffs.

5.Contact type:
It shows if the thermostat lets the current flow or stops it when the temperature is right.
6.Reset type:
The thermostat can either reset automatically or manually.
7.Insulation Resistance:
Measures the electrical resistance of the insulation, typically in the millions of ohms (MΩ). Values often range above 100MΩ at 500V DC.
8.Contact Resistance:
Measures the resistance between the contacts when closed, usually in the millions of ohms (mΩ), often below 50mΩ.
9.Life cycle:
The number of times the thermostat can be used.
10.Material:
The housing and contact materials, which are often made of stainless steel, ceramics, or high-temperature plastics.
11.Mounting method:
The way the thermostat is fixed to a surface.
1. Snap-action mechanism:
The KST thermostat uses a bimetallic disc that opens and closes when the temperature reaches a set point. This means the switch works reliably without arcing or slow transitions.
2. Bimetallic Design:
A bimetal disc made from two metals with different thermal expansion rates bends as the temperature changes, activating the switching mechanism. This ensures precise temperature control.
3. Precise Temperature Control:
Offers accurate temperature regulation within a defined range, typically with a tolerance of ±3°C to ±5°C.
4. Compact and lightweight:
KST thermostats are compact and lightweight, making them easy to integrate into small appliances, electronics, and industrial devices.
5. Strong and long-lasting:
The design ensures a long lifespan, with many models rated for over 100,000 switching cycles.
6. Works in many temperatures:
It can be used in temperatures from -20°C to over 300°C.
7. Reset type:
Automatic reset. It resets automatically when the temperature is back to normal.
Manual reset. You have to reset it manually when the temperature is safe.
8. Normally Open or Normally Closed contacts:
KST thermostats can be configured with NO or NC contacts, depending on whether the circuit should be closed or opened when the set temperature is reached.
9. Wide Electrical Ratings:
Can handle different voltages and currents (e.g. 125V, 250V, 400V and 5A to 20A), suitable for low-power and high-power appliances.
10. Safety features:
They often have safety features to prevent overheating and damage.
