High-quality customized sensors, thermal switches, and fuse services
Thermal switches (thermal fuse) and Temperature Sensor have to work in a fail-safe manner under any circumstances. Their natural operating environment includes cold, heat and humidity.
A thermal cutoff is an electrical safety device (either a thermal fuse or thermal switch) that interrupts electric current when heated to a specific temperature. These devices may be for one-time use (thermal fuse), or may be reset manually or automatically ( thermal switch).
A temperature sensor is a device that detects and measures hotness and coolness and converts it into an electrical signal. At YAXUN, we design and manufacture a broad portfolio of temperature sensors – including our NTC thermistors, RTDs, PT100/PT1000, and Ds18b20 – designed for efficiency and easy installation, with capacity to reliably integrate technology that responds to human behavior.

temperature sensor probe
Temperature probe assembly are used to make measurements of air, liquid or surface temperatures and are available in various forms such as thermocouple, thermistor (NTC) and PT100 to complement thermometers and temperature data logging instrumentation.

Thermal cut-off switch
A thermal switch is an electromechanical device which opens and closes contacts to control the flow of electrical current in response to temperature change. This thermal cutout (Automatic/manual reset) has a bimetal strip and a beryllium copper blade and the operating mechanism is based on the snap action disc thermostat (NC/NO).

Thermal fuse & current fuse
Unlike electrical fuses or thermal fuses, thermal fuses only react to excessive temperature, not excessive current, unless the excessive current is sufficient to cause the thermal fuse itself to heat up to the trigger temperature. A thermal fuse is like a mechanical switch that is spring-loaded to stay in the open position. An electrical fuse is essentially a thermal fuse with a well-established resistance and dissipation profile, and the current at which it fuses

Fuse boxes and fuse holders
Automotive/electrical fuse holders/boxes are holders used to install fuses, and their broad categories can be divided into: panel-mounted fuse holders, PCB-mounted fuse holders, lead-type fuse holders, rail-type fuse holders and automotive fuse holders. The fuse box is a box used to install fuses and has performance characteristics such as waterproof, fireproof, and high temperature resistance. According to different materials and shapes, fuse boxes can be divided into lead-type fuse boxes and fuse holders.

Recommend Several Automotive Motor Thermal Protectors
Automotive motor thermal protectors, also known as overload devices or inherent motor protection, are crucial for preventing electric motors from overheating and potentially failing. They detect excessive temperature or current and shut down the motor to prevent damage. These protectors are designed to protect the motor’s internal components, such as windings and insulation, from damage caused by overheating.
How to Correctly Install the Motor Thermal Protector?
To install a motor thermal protector correctly, ensure it’s placed in a location that accurately detects the motor’s temperature, typically near the windings or stator. Proper wiring is crucial, and the protection settings should be adjusted based on the motor’s design and the operating environment.
What is the Normally Open (NO) Thermostat Switch KSD301?
The Thermostat Switch KSD301 bimetallic disc operates in a Normally Open (NO) configuration. This means the circuit is initially open (disconnected) at normal temperatures. When the temperature rises to a predefined threshold, the bimetallic disc bends, closing the circuit and allowing current flow.
Normally Closed and Normally Open Temperature Switches
NC type is the “emergency brake” for safety protection, and NO type is the “temperature trigger” for intelligent control. The action logics of the two are complementary. The selection must strictly match the circuit function requirements (comprehensive).
Bimetallic Temperature Sensing Element of KSD301/KSD302
The bimetallic strip is the “temperature sensor + actuator” integrated component of KSD301. Its disc-shaped structure design and alloy ratio directly determine the temperature control accuracy and reliability.
What is DS18B20 Temperature Sensor?
NTC (negative temperature coefficient) temperature sensor is a temperature measuring element that uses the exponential decrease in the resistance of a thermistor as the temperature rises. Its core is a ceramic semiconductor made by sintering metal oxides (such as manganese, cobalt, and nickel), and the temperature is inferred by measuring the change in resistance. The following are its core technical characteristics, applications, and selection points:
