Thermal Bimetal Coil


Company Introduction

Wuhu Boton Automobile Parts Factory is a professional manufacturer with Boton brand and self-developement capacity. Our core competencies are  bimetal thermostatic coil strip and disc, thermometer, jumping disc toys, heating chamber for engine carburetors, auto generator regulars,various auto glass lifter motor protector, spiral spring for the auto, automobile and industrial.





Bimetal material consists of two or more metallic strips with different thermal expansion bonded together. This part being adjusted the angle causing movement by the hotter temperature, When heated up,  it bends in a pre-determined manner and can be used to monitor, measure and regulate temperature.

Thermal bimetal coil keeps temperatures normal


A thermal bimetal coil is a sensor designed to react immediately to changing temperatures.When an appliance becomes over heated,the bimetal coil opens the electrical circuit which immediately shuts off power.It is also used to monitor temperature,keeping a device at a normal operating temperature .


Automobiles provide one of the best examples of how a temperature switch works.An automobile can easily overheated especially during the hot summer months. The bimetal coil activates when  needed to keep engine fluids cool and the engine running smoothly .


Bimetal coil's main application are in thermostats and spiral spring for heating chamber or fan clutch, but they are also widely used in control devices of various industries.

1) The bimetal thermostats(thermal bimetal coils) that are used in refrigerator, household conditioner, car-conditioner,cold-storage, water dispenser, electricity heating device, washing machine.
2) The rigid producing and checking rules and the technologically mature procedures
ensure the reliability and performance of thermostats, which will meet the higher
needs of clients.
