The KST Adjustable Bimetal Thermostat is a reliable, cost-effective, and widely used electromechanical temperature control device. KST Adjustable Bimetal Thermostat operates on the fundamental principle of thermal expansion: a bonded bimetallic disc snaps from a convex to a concave shape at a specific calibrated temperature, instantly opening or closing an electrical circuit.
Jaye Heater Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of kst adjustable bimetal thermostat in China, also supports custom service. Welcome to wholesale high quality kst adjustable bimetal thermostat at competitive price from our factory.

KST Adjustable Bimetal Thermostat operates on the fundamental principle of thermal expansion: a bonded bimetallic disc snaps from a convex to a concave shape at a specific calibrated temperature, instantly opening or closing an electrical circuit.
These KST Adjustable Bimetal Thermostats are renowned for their simplicity, durability, and ability to function without an external power supply for the sensing mechanism. They are typically used for over-temperature protection (as a safety cutoff) or for basic on/off temperature control in a vast array of electrical appliances and industrial equipment. The "adjustable" feature allows you to set the desired trip temperature within a specified range using a calibration screw. As an OEM factory, Jaye can provide cutomized KST Adjustable Bimetal Thermostat.

1-Reliable Bimetal Snap-Action Mechanism:
The core component is a bimetallic disc that provides a quick, positive "snap" action. This ensures immediate opening or closing of the electrical contacts, minimizing arcing and extending the device's lifespan.
2-Precise Temperature Adjustment:
A central calibration screw allows for accurate setting of the trip temperature within a specified range (e.g., 50°C-200°C). This offers flexibility for various applications and fine-tuning.
3-High Electrical Rating in a Compact Size:
They are designed to directly switch high currents (e.g., 16A/250VAC) without needing a relay, despite their small and compact form factor, making them ideal for space-constrained applications.
KST adjustable bimetal thermostats are used in a massive range of applications where simple, robust temperature control or protection is needed.
1-Small Appliances: Electric kettles, coffee makers, rice cookers, water dispensers, bread makers, deep fryers.
2-HVAC Equipment: Electric heaters, fan heaters, heat exchangers, thermal curtains.
3-Motor & Transformer Protection: Over-temperature cut-off for motors, power tools, and transformers.
4-Industrial Equipment: Packaging machines, commercial catering equipment, industrial ovens (as a safety backup).
5-Consumer Electronics: Power supplies, battery chargers, amplifiers.
Welcome to ask for the quotation.
Q1: What is the difference between a fixed and an adjustable thermostat?
A: A fixed thermostat is factory-set to trip at one specific temperature and cannot be changed. An adjustable thermostat has a calibration screw that allows a user or assembler to set the trip temperature within a specified range.
Q2: How do I calibrate or adjust the trip temperature?
A: Turn the calibration screw (usually located in the center of the thermostat) clockwise to increase the trip temperature or counter-clockwise to decrease it. This should be done with a accurate thermometer in a controlled temperature chamber for precision.
Warning: Live calibration is dangerous and should never be performed.
