A bimetal thermostat is a type of temperature-control device that relies on the principle of bimetallic strips to regulate temperature. The term "bimetal" refers to the combination of two metals with different coefficients of thermal expansion, which are joined together to form a single strip. This strip bends when exposed to temperature changes, and this mechanical movement is used to activate or deactivate the thermostat, thus controlling the temperature in various devices.

    What is a Bimetal Thermostat?

    A bimetal thermostat consists of two metal strips that are fused together. These metals expand and contract at different rates when exposed to heat. One metal typically expands more than the other as temperatures rise. When the temperature increases, the bimetal strip bends due to the unequal expansion of the metals, triggering a switch that can either open or close a circuit. This action helps regulate the temperature of the device in which the thermostat is installed, turning on or off the heat source accordingly.
