    A bimetallic strip is used to convert a temperature change into mechanical displacement. The strip consists of two strips of different metals which expand at different rates as they are heated, usually steel and copper, or in some cases steel and brass.The different expansions force the flat strip to bend one way if heated, and in the opposite direction if cooled below its initial temperature.
