A bimetal thermostat is a vital component in numerous electrical and mechanical devices, widely used for regulating temperature. This type of thermostat uses the physical properties of two different metals that expand and contract at different rates to control the activation or deactivation of heating or cooling systems. In this article, we will explore the working principles, applications, and advantages of bimetal thermostats.

    What is a Bimetal Thermostat?

    At its core, a bimetal thermostat consists of two metal strips that are bonded together. These strips are made from two metals with distinct coefficients of thermal expansion. When the temperature changes, one metal expands more than the other, causing the bimetallic strip to bend or flex. This movement can be used to open or close an electrical circuit, turning a device on or off based on the set temperature.
